"Paintbrush was taking a leisurely walk across the grass, enjoying the afternoon sun. They were on their way to find their girlfriend, Lightbulb, who had probably just woken up. They closed their eyes as they whistled and skipped, turning a corner around a tree, this is the first time in a while that they’ve actually been really happy. They almost didn’t notice it at first, but when they opened their eyes and looked around for Lightbulb- Their eyes suddenly snapped open and they almost fell backwards in surprise.
“L-L-Lightbulb?! Is that you?” Paintbrush exclaimed, and looked up at Lightbulb, who was towering about 9 feet above them, even though she was sitting down. She looked sleepy, blinking a little bit before she noticed the tiny-by-comparison Paintbrush at her side.
“Of course it’s me, Painty, don’t be a silly-billy.” Lightbulb rubbed her eyes and looked down at her partner. “Woah, did you get smaller or something?”
With Lightbulb’s giant hand thumping on the ground next to them, Paintbrush stumbled back a bit. “Wh-Wh-Wha… I think you might’ve gotten bigger!”
Lightbulb suddenly lifted her arms and began to stretch loudly, her face scrunching up a little as she leaned back, a sound almost like stretching rubber accompanying her as she stretched out her legs and grew taller and larger for the entire duration of the stretch- a few feet more, more, more- now towering over the tiny painty, almost the size of a regular paintbrush to her.
Paintbrush stumbled back and was nearly crushed by Lightbulb’s now-massive feet.
“Woah… cool!” Lightbulb said. Paintbrush’s heart was racing so fast that they nearly couldn’t contain the squeaking noise they made as Lightbulb’s hand came close to them- It was now able to grab Paintbrush by the handle and pick them up with ease.
“Hiiiiiii tiny Painty!” Lightbulb said, her voice was much louder now.
“What happened to you??” Paintbrush had to shout to reach Lightbulb’s ears.
“I think something might’ve happened while I was sleeping. Or it was that weird… mushroom thingy that I ate.” Lightbulb said.
“You ate a weird mushroom thingy!?” Paintbrush exclaimed.
“Yeah. It looked like one of the power-up ones from… What’s the name... Luigi?” Lightbulb said.
“LIGHTBULB!!” Paintbrush said, slightly angry, still quite nervous.
“C’mon Painty, don’t be a bummer. We can get Mephone to change me back.” She continued, “Until then I could totally pick you up and paint with you,” She chuckled.
Paintbrush let out a small gasp. “H-huh?”
“You’re totally like a little doll. It’s kinda cute.” She said. “I could totally just-” Lightbulb reached down and suddenly grabbed the flustered, nervous Paintbrush by the handle and lifted them up to her face.
“Hiiiii!” She said, giving the tiny Paintbrush a big kiss on the cheek that took up almost the entire side of their face. Paintbrush was breathing hard, flushed, heart beating like a hummingbird.
“Huh? What’s the matter? Don’t worry, I won’t hurt ya.” Lightbulb said, and slowly stood up and started to walk, her footsteps thump thump thumping on the grass and almost bowling over the vending machine. “Whoop, gotta be careful.” She said.
“D-Do you know where you’re going?” Paintbrush managed to say.
“I dunno. I’m just takin’ a walk.” She said.
“Well, watch where you step!” Paintbrush added.
Thump, Thump, Thump-
Lightbulb spotted a little light green spot in contrast to the grass, and she gasped. “Is that little Test Tube?” And the little green spot turned around and her eyes widened as she began to take in the sight she was seeing.
“L-LIGHTBULB?!” Test Tube said.
“Yup!” She said. “I’m huge, You’re tiny!” She said.
“WHAT HAPPENED TO YOU?!” Test Tube shouted.
“SHE ATE A WEIRD MUSHROOM!” Paintbrush shouted back.
“OH!” Test Tube replied.
With that, Lightbulb reached down and picked up the tiny Test Tube and sat down with a small crinkle. Wait, crinkle? Lightbulb looked down, and realized that she had suddenly sat on the tiny Fan, and she quickly stood back up.
“Oh, sorry red paper.”
The crinkled Fan gave a weak thumbs up and peeled himself off the ground, shaking himself off.
“Woah. Lightbulb, you’re HUGE!!” He said.
“No DUH!” Lightbulb said. “You’re tiny!”
“Do you realize what this means?!” Fan said. “No really, do you realize what this means? Cause I don’t.”
“WE CAN PROBABLY GET MEPHONE TO CHANGE HER BACK!” Test Tube shouted down to Fan.
“Aww man, but it’s fun being huge.” Lightbulb was clutching the two smaller objects like dolls.
Lightbulb took another step, and her massive pawlike foot loomed over Fan, who was still recovering from being sat on, and... squish! Lightbulb put her whole weight on the poor flattened Fan and spread him across the dirt… crushing him again?!
“Oh. Sorry, again.” Lightbulb lifted back up her foot and peeled Fan off the ground and put him on top of her head like a piggyback, and sat down. Fan was babbling nonsense, dizzily trying to stay sitting up. He shook himself off again, and looked around. The view from up there was insane! He could see so far from up here- Lightbulb was as tall as a house! Lightbulb put the two other objects in the middle of her legs, that were sitting criss-cross- They were so small and fragile compared to the massive clumsy Lightbulb. She smiled and sighed.
“Isn’t this kinda nice?” Lightbulb said. “I didn’t know it could be this fun to be huge.”
She sighed. Paintbrush relaxed a little bit and leaned against the inside of Lightbulb’s leg, While they were still a little nervous… Yeah, it was kind of nice. Test Tube, on the other hand, was taking pictures with her phone and frantically typing notes like this was the next scientific discovery. Paintbrush could see Fan resting on Lightbulb’s head, his eyes sparkling as he looked out. Paintbrush smiled and closed their eyes again."
