"Jake," Finn says laying on the ground, thinking, "How big is the world?"
"Pretty big man," Jake says, making spaghetti on the stove, "Like, huge. Way huger than I can stretch. But most parts haven't been explored since the war, so we don't know what's out there, outside of Ooo. The bravest people in the world go and check it out."
"I'm really brave." Finn says, sitting up.
"Yeah, but are you the BRAVEST." Jake says.
"I could be!" Finn says, standing up, "With DETERMINATION.
"Uh huh." Jake says.
"I'm serious!" Finn says, "You know what, I'm gonna walk to the end of the world. TODAY."
"Bro, there IS no end of the world." Jake says, "It's like a ball. After a long time you'll end up back where you started. Like in a circle. Except there's supposed to be this big chunk missing. I dunno if it's true. Nobody's come back to talk about it."
"Then I'll see!" Finn says.
"But there's also, like, water in between n' stuff." Jake says.
"Then I'll swim!" Finn says, "I ain't afraid of no ocean anymore!"
"Fine," Jake says, "So when are you going to start your adventure?"
"Right now!" Finn says, going towards the door, "You wanna come with?"
"Nah," he says, "I wanna eat my s'ketti. Maybe I'll join you if you wanna do it again."
"Kk, them I'll just ask Flame Princess." Finn says, "I don't wanna walk around the world alone. That'd get boring."
"Okay, but-"
Jake can't finish his sentence because Finn is already out the door.
He tries to think of what he was going to say, but he's distracted by the delicious spaghetti and forgets it.

Finn knocks on the door of Flame Princess's house. After a few seconds she comes out.
"Hey Finn." she says.
"Hey FP." he says, "Wanna walk around the world with me?"
"Hm, I dunno." she says, "I was planning on burning that tree down today. It's blocking my view in the window."
"It'll be fun!" Finn says.
"How fun?" Flame Princess asks.
"Well," he says, "About medium fun. But they'll be a lot of adventure!"
She thinks about it for awhile.
"Okay. I'll go."
"Awesome!" he says, "We should go to Tree Trunks to get us to bake some pies for the road."
"But how could the trunk of a tree make us pie?" FP asks.
Finn laughs,
"No no, Tree Trunks isn't actually a TREE. That's just her name. She's an elephant."
"But aren't elephants big and scary?!" she says, concerned.
"Most of them, but not Tree Trunks." he says, "She's old and sweet. Like a grandma."
"Oh, like my Grams." she says.
"Was she old and sweet too?" he asks.
"No. She was evil." she says.
"Okaaay…" Finn says, "Let's just get the pies."

Finn and Flame Princess crouch over on the ground in the forest.
"Okay, so we've got some pies in case we get hungy." Finn says, patting his backpack.
"Tree Trunks was nice," Flame Princess says, "But she kept making out with that pig. It was weird."
"I guess," he says, "But they're old and in love and junk."
"Ah," she says, "Are we in love?"
"Uhhh…" he says, "NAKEDBABIES!"
"What?" she says, turning around.
"Nevermind." he says, "Let's go!"
They walk until the sun starts to set, and then they reach water.
"Okay," Finn says, "Guess we'll have to swim!"
"But I'm made of fire," FP says, "I'll die if I get into the water."
"Oh, yeah…" Finn says, staring at the water, "I guess I didn't think this through…"
"Then what do we do?" she asks.
"Hm…" he says, "Wanna go back to my place and we can eat some pie with Jake?"
"Sure!" she says.
They could walk around the world another day.
