Here is my part of our little trade art I did with  koopa-stories

I said I haven't ideas for a story but we both did a roleplay so... here is the story.

Cloud was close of a playground, he gets a little hungry so, he sees a weird blue mushroom, looks tasty, so he eats him but suddenly shrinks to small like a bug, so he needs get help of somebody, he across the fence who is around the playground. "Wiiiiiiii" someone shouts, but was a it was a shout of fun, he say someone, looks like a Koopa kid with the egg from where it was born split in two, a half on his head and the other one used like a pants, he was Jr. Troopa, Cloud run into the swing where Troopa is having fun :D

So he tries to ask help, but Troopa says, "Oh man, this should be funny if I had a micro friend, or a micro toy" he laughs while swags, Cloud get highly strung, thinking the worst, "Oh no" he said, Jr Troopa beards him, so he get down of the swing and cakes to the shrunken Koopa...
"Hello there little fella" Jr.s say
"Hi" Cloud replies a bit scared, "What are you doing in my own playground? you like it?" Jr.s ask with a playful face
"Help me, I was shrunken down by..." He stops, what would think jr Troopa if he says he shrunk himself with a mini mushroom? "Mario, he shrink me"
"That ugly plumber!" Jr Troopa say while picks Cloud, "Don't worries, I will help you", he said while he take of his shoe, "Meanwhile you will get inside, I need my wand and maybe Mario makes you smaller" Jr Troopa Drops Cloud inside his shoe and wears on, "Hey, let me out, here smells bad"
So Jr. goes for his wand for shrinks Mario, but he will be careful with his new micro friend, or not and he will be his new toy.
