this fanfiction will be about The Great Mushroom war. If you don't know what that is look it up. It's about like a big war that happened that wiped out all the humans but Finn. But this has been bugging me for a long time. If all the humans were wiped out how was Finn even born. This is my theory now i'll shut up.

It was a average day in the land of Ooo. Finn and Jake were bored. They played Bmo but still bored. But that was about to change.

"Dude i'm so bored let's do something" Finn said as he was playing Bmo.

"I don't know about you but i'm making me a sandwitch" Jake said as he but mustard on his sandwitch.

"Whatever man" Finn said.

"Dude I just made the most perfect sandwitch in the history of sandwitchism the ham, turkey, the tomatos, the hole caboce" Jake said as he was about to take a bite.

"Eat it on the way come on" Finn said as he took Jake's hand and ran out the door

"My sandwitch" Jake said as he stretched to grab it

They were walking around the land of Ooo to find something to do. They didn't find anything it was a boring day. Even the Ice King wasn't stealing princesses.

"Man there's nothing to do here got any ideas jake" Finn said.

Jake was mubbleing as he had a big chunk of sandwitch was in his mouth.

"What the dude your still your still eating it it's been like half an hour" Finn said stareing at him

"Dude you just can't plop it in your mouth hole you gota savor the food or it just taste like crap" Jake said as he took another bite

"Ok what ever you say bro" Finn said as he was looking around then he found something.

"Hey man I think I see something" Finn yelled as he entered the cave.

"Man there's nothing in here just a hole bunch of rocks and dirt" Jake said.

"Yeah man I guess your right just really bored I guess sorry man" Finn said.

"It's all cool man" Jake said as he put his hand on the wall making the floor open and Jake falling in.

Jake screamed

"Don't worry buddy i'll save you" Finn said as he jumped in.
