"(Y/n)! You give that back, NOW!" Fell ordered, you were laughing as you ran with Fell's scarf. "Swap! I got it! I got it! You owe me a cookie!" You yelled as you ran into the kitchen. "YOU told (y/n) to steal my scarf?!" "Heh. Maybe." Fell growled before you threw his scarf into his face.

"You little-!" Fell chased you as you ran. "B! B! I need a pillow!" You squeaked as you forced your legs to carry you quicker. "You got yourself into that mess. You can get yourself out." WingDing commented as he walked by.

"Oh dear... Did you steal Fell's scarf?" Starlord asked, "Umm... Maybe?" You said before continuing to run from Fell. "WHERE IS SWAPFELL OR MAESTRO WHEN YOU NEED THEM?!" You yelled as you ran down a hallway. "Hmm?" Maestro hummed as you ran towards his room. "Maestro! Help me! Please!"

Maestro pulled you into his room before Fell saw you. You hid in Maestro's closet as Fell trotted in. "Hey, Music Note, have you seen (y/n)?" Fell asked as you stayed quiet in the closet. "No I have not. Have thy try the fun room?" Fell left before Maestro opened his closet.

"Thy owe me." "I know. I know." You walked out as you caught your breath. Maestro rubbed your back as you panted and laughed at the same time. "Swap is making cookies, want to get some?" You and Maestro walked out of his room before going to the kitchen.

"Hey! You got away from Fell!" Swap said cheerfully. "Yeah. Maestro helped me." You replied as Maestro ruffled your hair. "What about 'getting away from Fell'?" Swapfell asked as he walked in. "Long story short I stole Fell's scarf and he chased me until Maestro hid me in his closet." You explained.

"Nice." Swapfell said as you both high fived. "I wouldn't celebrate. Fell's coming back." B said from the dining table. "Please, he'll get over it." Swapfell huffed before he took two strains of your hair and made them point up. "Hey guys," you huffed as the guys snickered, "I found out why (he/she) is so much trouble!"

You got out of Swapfell's grasp and got two cookies. "Hey-!" "You owe me Swap." Swap mumbled 'oh yeah' before Fell took both the cookies. "Hey! Fell!" "Hey, you stole my scarf. I steal your cookies. That simple."

You growled before getting another cookie. "Heh, stinker." Fell chuckled as he ruffled your hair. You stuck your tongue out at him before eating the cookie. "So, Swapfell," Swapfell looked at you as you smirked, "would I'd be asking for a death wish if I took your jacket?" Swapfell smirked back.

"(Y/n), you'd be asking for ten death wishes." You snickered before enjoying a somewhat peaceful afternoon with the guys.

"WHAT DID I JUST SAY?!" Everyone howled in laughter as you ran off witg Swapfell's jacket. "LIVING LIFE ON THE EDGE!" You screamed as Swapfell chased.

"I AM GOING TO MURDER YOU!"

"Not if you can't catch me first!"
