Like most stories ideated by him in my gallery, it involves shrunken characters having to get the attention of an unaware giantess and avoid her stomping feet, but this time we leave the "crapsaccharine world" of Equestria and dive into the absolutely MENTAL world of one of the most nonsensical kids' shows ever created: Dinosaur Train.

The very long title plays with the actual title of one of the show's episodes, "Great Big Stomping Dinosaur's Feet", which apparently is about some dinosaur species having really big feet, but in this context the title clearly assumes a different meaning, because the story sees Buddy the T-Rex and Tiny the Pteranodon getting shrunken down by aliens (seriously, with all the crazy stuff that happens in the show, why not aliens?), having to avoid being stepped on by their gargantuan mother and learning a lesson about not being needlessly cruel to bugs (pretty rich coming from me, I know, but don't take this seriously XD)

Alright, as always I hope you like the story.

---

On a nice and peaceful day, a small millipede was just walking in the middle of the grass, which to the little creature was like a thick forest. Nothing made the insect sense danger, so it simply proceeded its walk, looking for food or maybe for a mate, or anything that his simple life made only of instinct could possibly need.
Its senses didn't make it question the sun getting darkened, but it did feel the ground vibrating and it heard the crunching of grass getting stepped on, like some bigger creatures were approaching; the millipede was now in alert mode, its walk became more careful, but it was still impossible for him to foresee the scaly orange wall slamming right in front of him with a loud “STOMP”, destroying several blades of grass and blocking the millipede's way.
The insect turned the other way and began to crawl away from the monstrous dinosaur paw as fast as it could, accelerating even more when the foot began to go up and threatened to squash it. Thankfully the little creature got out of its way just when one of its claws was barely touching it.
But just when the little being thought it was finally safe, a second foot stomped in front him, this time a smaller green one, and it barely missed its puny body, in fact its tiny head touched the scales between two of the clawed toes.

“ROAAARRR!” A squeaky feminine voice yelled from up above, “I'm no longer Tiny, from now on you will call me GIANT!”

The green foot moved and threatened to land right onto to the millipede to crush it into goo, but just as it was dangerously close to the helpless running bug, it suddenly stopped in midair while the voice of a third, even bigger creature cried: “Tiny! Buddy! What are you doing?”

“We're playing with bugs,” Buddy the T-Rex answered to his adopted mom, “we are like giants to them, so it's lots of fun stepping on them!”

“Yeah, it's awesome!” Tiny the Pteranodon agreed “I feel so BIG when I squash them with my feet! I've already stomped on so many of them, they can't escape the wrath of the biggest Pteranodon ever!” She raised one of her little feet and looked for the millipede, but in the meantime it had ran away unscathed.

Mrs. Pteranodon crossed her winged arms and glared at her children. “Now kids, these aren't good games to play! It's very cruel to kill small and helpless creatures for your own amusement!”

“But mom,” Tiny complained, “bugs are so little and insignificant and there are so many of them!”

Buddy defended his stepsister: “Yeah, besides we often can't help stepping on them because we don't even notice them! I bet even you keep crushing lots of bugs under your feet every day without realizing it! And remember when we have to kill mosquitoes before they suck our blood and make us feel sick?”

But the adult Pteranodon didn't change her expression. “That's true, there are many bugs and we often can't help stepping on them, as it is true that at times we are forced to kill them for self-defense, like we do with mosquitoes, but that's not an excuse to torture them just for fun when they haven't done anything to you, that just makes you a big bully! How would you feel if a bigger creature decided to squash you just to play a game?”

The little T-Rex sighed, knowing he didn't have a real retort to that. “I guess it would be no fun at all...”

Tiny on the other hand was much more stubborn. “But there isn't a bigger creature around us wanting to crush us, is there?”

Mrs. Pteranodon shook her head. “Tiny, Tiny, Tiny, we'll have to talk about this! Anyway, it's almost dinner time, so make sure to come as soon as I call you, now as a punishment I want you to wash your feet and make sure there are no dead bugs under them when you come to eat, if I find any crushed little creature under your soles when I check them, you are grounded!”

Mama Pteranodon Flew away while the two kids began to grumble and express their annoyance with the punishment, but they didn't oppose to it either so they began to somberly walk towards the river nearby to wash their little stompers.

“It's not fair!” Tiny whined to her brother “Every single time we find something fun to do it turns out we CAN'T do it! I hate this so much!”

“I know, it stinks... but I think mom has a point.”

“A point?! Well do what you want, Buddy, I'm not gonna stop having fun with puny little animals just because mom is like 'blah blah blah, not cool to kill', if I see ANYTHING small on the way to the river, I'm gonna SQUASH it and wash my foot afterward so mom will not find out!”

Buddy shrugged. “Have it your way.”

Tiny spotted something in the grass and said with a mischievous smirk: “Lookie lookie, there's what I needed to see!” She pointed at some very strange bug, it was quite shiny and it didn't move at all, probably some weird type of beetle, and all around it there were what appeared to be ants...

***

“Sir, the whole team and I have been scouting the area for hours,” a tiny alien said to his superior, “but there really is no trace of any material that could be useful to our world, so if I can make a suggestion, maybe we should just leave this planet.”

The other alien touched his chin as he pondered on what he had just heard. “I see... very well then, time to fly again. Besides, I wouldn't wanna meet one of those enormous creatures we saw before we landed...”

Just as they were beginning to get back on the starship, the aliens were suddenly startled by a short but strong earthquake, which soon was followed by another one, and then another, and then another one again, each tremor getting more violent...

“OH NO, LOOK!” A terrified alien soldier cried, pointing at two towering approaching figures.

There were two colossal creature stomping closer to the starship, but the green one in particular terrified the tiny beings because of the expression of pure malice she had while looking right at them. But that was nothing compared to what she did when she was so close she was obscuring the sun: she raised a terrible foot and let it loom over them, clearly intending to let it come down to crush them all!
One of the extraterrestrial little men took out some sort of large rifle and automatically shot a green ray at the giant creature, and also at the orange titan by her side, and just like that the giants shrank down in the winking of an eye, becoming as small as the aliens in midair and then falling down, disappearing from the little spacemen's sight in the middle of the very tall grass.

“Why did you shrink the other giant too? It didn't look dangerous!”

“Looks can be deceiving, you know? Safety comes first!”

“Whatever, let's just get out of this horrible place before they see us! I just hope those two natives will be fine until the effect of the shrinking ray wears off...”

And so the microscopic army immediately boarded the ship and took off, flying away until the alien vehicle was just a disappearing speck in the sky.

***

Buddy got up slowly, feeling dizzy and in a bit of pain because of the bump, the softness of the plant he had landed on saving him from certain death. “Ow... my head...” he grumbled.

The young Tyrannosaurus looked around himself and saw something truly shocking: all around him there was a giant version of what he used to see as just soft grass beneath his paws, now it was like a strange forest that he walked in like a teeny tiny ant!

“This... this can't be real... I'm dreaming, right?” Buddy tried to pinch himself multiple times, but he was still in the middle of the jungle of blades of grass. Then he remembered his adopted sister...

“Tiny? TINY? WHERE ARE YOU?”

“I'M OVER HERE BUDDY! HELP ME!” The young Pteranodon's voice called from not so far, sounding like she was both scared and hurt.

Buddy ran towards where the voice came from as fast as he could, moving the giant green vines with his hands when they were in his way, thankfully they were still soft and easy to move.
Soon enough, the little T-Rex found his adopted sister, curled on the ground and moaning with tears in her eyes as she massaged one of her wings.

“Oh no... Tiny, did you hurt your wing?”

“Yes, when that green light hit me I suddenly fell, I was too scared to fly so I hit my wing, it hurts so much, I can't move it!”

“Hang in there, try to keep your wing relaxed, can you stand up and walk?”

“Yes, I think I can... Buddy, where are we?”

“We're in the middle of the grass! That green flash made us as small as bugs!”

Tiny took a look around and finally realized what she had been guessing but refused to believe until now that her brother was telling her it was real, and she couldn't even answer, she just began to whimper and sob while Buddy helped her to get up and walk.

“Please Tiny, don't panic, we need to find someone who can help us!”

“But who could possibly help us when we're so small and pathetic? We're just like all the creatures we've crushed, they're taking revenge, this time it's OUR turn to be squished!”

“Tiny, stop it, I'm scared myself and you're making it worse! Perhaps mom will come looking for us, she doesn't want to squash bugs!”

***

In the meantime, Mrs. Pteranodon had just finished putting several leaves on a rock so she and her children could eat them together; all the other members of the Pteranodon family were already there, only Tiny and Buddy were missing.

“Tiny! Buddy!” The mother called “Come here, it's dinner time!” She got no answer... she tried to call again, but still in vain. “Uh, weird, even when they're cranky or disappointed they never miss dinner... I'd better check those little rascals out.”

So Mrs. Pteranodon took off and flew right towards where the two little dinosaurs were playing before.

***

The shrunken little dinosaurs just walked in silence for what felt like a very long time, Tiny still massaging her aching wing and Buddy looking around himself with his usual curiosity.
He actually found that new environment almost beautiful despite his awareness of how dangerous it was to be at that size, it all looked kind of peaceful and the giant blades of grass were of a bright green, and the very tall flowers looked almost like majestic and colorful trees... but soon his sense of wonder had to be replaced by terror when he saw an ominous flying figure obscuring the sun.
Surprisingly, his fear diminished only slightly when he realized that the gigantic flying creature was his mom. She was so huge... no matter how hard he tried to remember she was still his loving step mom, Buddy couldn't help being intimidated by her size.

“Mom!” Tiny cried, revealing how her feelings weren't any different “My goodness, she's so BIG!”

“Well, she could still save us,” Buddy said, forcing himself to sound less scared than he truly was, “look, she's getting closer...”

As soon Buddy was done talking, both little dinosaurs felt a strong and overwhelming wind blowing, in fact it was like some sort of tornado, and the shrunken kids needed to grab something in order not to fly away.

“I don't believe it, is it her wings doing this?!” Buddy yelled in bewilderment.

The storm seemed to go on for an eternity while the massive Mrs. Pteranodon appeared to be landing in slow motion, her massive wings looking unusually majestic, and when her talons finally touched the ground, the wind ended but it was replaced by something equally scary: the earth shook with tremendous violence, it reminded the children of Daphne Daspletosaurus and her family slamming their large feet but it was even stronger and not playful at all!
Even though the adult Pteranodon was still quite far, Tiny and Buddy could still see her towering figure pretty clearly. She was almost unrecognizable even though her features were the same and she clearly still had the face of the loving mom that she was, but her sheer size nearly eclipsed all of that and turned her into some kind of terrifying monster.

“TINY? BUDDY? WHERE ARE YOU?” The giantess called with a deep, echoing and utterly scary voice that barely sounded like the one of Mrs. Pteranodon.

Buddy and Tiny hugged each other tight and trembled uncontrollably as their small ears ached because of the booming noise.

“Buddy... mom is scaring me!”

“I know, she's massive... but she has to see us, or else how can she help us? Come on, let's try to call her!”

And so the children began to shout things like “MOOOOOOM!!! DOWN HEEEERE!!!” But it was like they weren't even saying a word to her, and not even jumping up and down helped at all.

“It's no use, Buddy! Our voices are too feeble and she's too huge! Urgh, if only I didn't hurt my wing!” Tiny even tried to take off, but her wing was still in too much pain.

“Wait, don't make it worse for your wing, I'll try to climb that mushroom, maybe that will make me more visible, you wait here.”

And so Buddy put his only plan in action and climbed a tall mushroom nearby. Meanwhile, his gigantic mother kept calling and nearly making him deaf: “GUYS, IT'S DINNER TIME, THERE'S NO TIME TO PLAY HIDE AND SEEK, COME OUT THIS MINUTE!” This time she sounded even scarier due to how stern she was, but Buddy kept climbing until he was on the top of the mushroom.

“MOOOM!!! PLEASE LOOK DOWN, I'M DOWN HERE AND I'M SMALL!” Once again, it was all in vain. And then it got worse when Mrs. Pteranodon began to walk...

When the giantess' massive scaly foot touched the ground, the terrible earthquake from before came again (only slightly less strong since she wasn't landing with both paws), accompanied by a mixture of a loud “BOOM” and a “CRUNCH” of trampled green.
The shrunken dinosaurs lost their balance and Buddy nearly fell off the mushroom, and in that moment he realized he had to get off immediately because Mrs. Pteranodon was coming right towards him.

“Buddy, jump down, I'll catch you!” Tiny yelled, confident that she could make it despite her sore wing.

BOOM, BOOM... The titan kept stomping closer until the sole of her foot was right above Buddy, who looked up and screamed with terror before jumping down right in the arms of Tiny.
As the two kids rolled, the gigantic foot of their mom squashed the mushroom with a loud and gross SQUELCH, and it barely missed her children, who got in the dark space between two of her toes.
When the world stopped shaking, Tiny and Buddy stopped doing the fetal position and looked at the green walls around them, then the foot got up again with a rumbling noise, revealing a devastated place full of flattened grass and the remains of the mushroom. They couldn't help weeping at the vision.

“Buddy... that was horrible!” Tiny cried between her sobs “Mommy's foot... it was HUGE and... she nearly stomped on us!”

Buddy dried his tears and tried to be strong. “Well, she didn't mean it... and now she shouldn't risk to step on us again...”

But the little T-Rex had spoken too soon, because soon enough the giantess turned around and began to stomp in their direction once again, still calling with her monster voice “TINY! BUDDY! YOU'RE MAKING ME MAD NOW!”

The destructive food of Big Mama loomed over her children's head again, and this time they could clearly see a crushed little bug stuck to her sole, not dead yet but pretty close to its head, pathetically moving its puny little legs...
Buddy and Tiny managed to jump out of her way in time before they became pancakes, while the green stomper made everything violently tremble again.

“It's no use, Buddy!” Tiny choked up “It's the end, we are bugs at the mercy of mom, she's going to squish us both!”

This time her brother didn't know what to answer, he could only hold Tiny and cry with her. Meanwhile he looked at his giantess mother and noticed she was doing something strange: her expression changed as she began to smell the air, like she was trying to use her nostrils after her other senses had failed to find her kids.
Even though her nostrils were so small, the tiny dinosaurs could still hear them inhaling and exhaling fast while Mrs. Pteranodon raised an eyebrow, realizing that the familiar smell of her children was much closer than she could possibly think.

“Tiny, look, she's looking down!”

Indeed the huge beast was bowing her head, smelling the ground, once again moving closer to the kids, who were finally regaining some hope and decided to stay where they were.
The huge beak of Mrs. Pteranodon was now touching the forest of grass, the noise of the vacuums that were her nostrils still echoing, getting louder as the giant face got closer, and little by little the siblings could feel the air going in and out of those holes in her massive beak as their mom kept looking bigger and bigger.
The tip of the giant beak finally poked the kids, who remained still despite the terror they were feeling, and after some more sniffing, the mother got up again and stared at the two strange specks in the grass for a moment... a weird thought crossed her mind, it sounded absurd but she had to get to the bottom of that.
But in that moment, hope suddenly disappeared again from the heart of the micro dinosaurs when the giantess opened her beak and quickly hit the ground with it, barely missing her children, who jumped with unexpected agility as a smaller quake shook the earth.

Buddy stared for a moment at the small hole left by mom's beak, when he heard Tiny screaming “LOOK OUT!”

And just in time they avoided the monstrous maw of Mrs. Pteranodon again. The same thing repeated itself a few times, until the screaming dinosaurs found some kind of hole in a bunch of little stones and hid inside of it without thinking too much about it.

“This is it, Buddy... mom wants to EAT us! We're no longer her children, we're her DINNER!”

Buddy gave his sobbing sister a tight hug, once again not knowing what to say... but someone else did: “kKds? Is that really you? Please come out, I'm sorry I scared you, I was just trying to pick you up and take a closer look at you! I don't know how you got so small, but if you're really Tiny and Buddy, come out of there, please!”

The booming words of Mrs. Pteranodon were manna from heaven. No longer fearing their own mom (not that much at least), the carefully began to walk out, feeling another earthquake as Mrs. Pteranodon lay down to look closer at them without having to put them in her beak.

In front of the two dinosaurs there was now the big eye of their mother, and soon they heard her booming voice gasping “Goodness gracious, it's really you!”

Just when the kids were going to tell the giantess the whole story, they felt funny, like their skin was stretching, and the environment around them began to become smaller and smaller while they grew bigger and bigger until they regained their original size.
Overwhelmed by joy, the two hugged and kissed their no longer monstrous mom, who did exactly the same with them.

“Oh, my babies, I have no idea what happened but I'm so glad you're fine, it must have been scary to you being so little!”

“It was REALLY scary!” Tiny squeaked “I don't know what happened, we saw some kind of green light and then BOOM, we were no bigger than bugs, my wongs got hurt and I couldn't fly, and then you arrived and... oh dear, your feet were HUUUGE, and they went BOOM, BOOM, and we nearly went SPLAT and...”

Buddy interrupted her sister. “OK Tiny, calm down, we're big again now. And sadly it's true mom, you nearly stepped on us by accident, but that's OK, you didn't mean to and the effect of whatever made us small has run out. And... I guess this adventure taught a valuable lesson to Tiny, right sis?”

Tiny sighed. “Yeah... now I know how horrible it is to be a puny and helpless bug at the mercy of a giant, I will never play those cruel games again!”

Mrs. Pteranodon caressed Tiny's head. “I'm glad this strange misadventure made you think about that. But most of all I'm glad you're OK and you managed to survive my walk, you are my precious, crushing you would have been way too horrible. But now let's try not to think of this again, we're fine now. Don't worry about your wing Tiny, it'll heal soon if you get plenty of rest. Let's go now, dinner's ready.”

And so the family was reunited again, and the two most adventurous members had a weird and interesting adventure they were going to tell anyone who'd like to hear it. If only they had known the bizarre truth behind their shrinking...
