What's up? This is my Adventure Time short story. Only one chapter, in fact.
Marceline was hanging out with Finn, who was now about 17. "Hey Finn, wanna play that song that we first sung together? It is called, Daddy Why did you Eat my Fries." "Sure, Marcy!" Marceline went and grabbed her bass axe guitar. She grabbed two microphones, some drums, and speakers. It took her a while to get them all, but she did it in less than 3 hours! Then she went to grab her bass axe guitar. "WHAT!?" She hissed. "I dunno where it went, MarMar." Finn tried to comfort his vampire friend. But what they didn't know, Jake was nearby, hiding behind a rock. He chuckled and turned to the bass axe guitar. "I love it when I pull pranks on those two lovebirds!" He giggled. Jake Jr was with him. She laughed too. Anywho, Marceline was looking all over. Then she approached the rock. "Jake, Jake Jr, what are you doing with my bass axe guitar?!" She hissed. "We were pulling pranks on you because we were really bored." Both Jake and Jake Jr said. Marceline managed to laugh. Finn ran over to her. "Jake, what have I told you about pulling pranks on us, bro!" Finn scolded Jake in a jokingly way. "WE GOT BORED, BRO!" Jake answered Finn. Then everyone laughed.
How was that? This was the only idea I could come up with Lol. :3 Peace out!
