BMO, Finn, and Jake traveling along a twisty mountain road.

'''Finn: '''[singing] Walkin' to the castle, castle walkin' to, doo-doo-doo, doo-doo-diddly-doooo...

[''they finally arrive at PB's castle'']

'''Peppermint Butler: '''Oh, goody! The plumbers have arrived. Heh heh heh, look at them, so wise when it comes to toilets and potties...

'''Princess Bubblegum: '''Uh, they're just Finn, Jake, and BMO. They're the winter caretakers for the castle.

'''Peppermint Butler: '''Yes... they sure are.

[PB takes the 3 on a tour of the castle]

'''Princess Bubblegum: '''This castle has quite the history. It was built during the great zombie invasion of 1302, and was used as a prison, an insane asylum, and even an undewear factory at some point...

[''they stop in front of the elevator, which opens and disgorges a'' river of blood'']''

'''Princess Bubblegum: '''Hmm, that's odd. Oh, well, next we will take a tour of the bathroom area.

Outside, the camera stars high above a hedge maze and zooms down to

Peppermint Butler watering one part of it.

[''a roar and some grunting is heard, and then a firey hole burns through the hedge'']

Finn is thrown through the burning hole.

'''Finn: '''Hey, Pep But, me and Jake slayed that dragon for you..

'''Peppermint Butler: '''Oh, my, Finn, look what you've just - [''thinking''] No, no, go easy on him. After all, he is the only one of his kind...

'''Finn: '''Dude, please don't mention me being the only human and all... gets me depressed, ya know?

'''Peppermint Butler: '''[''gasps''] Oh, my! You must have... [whispering] "The Shmowing"!

'''Finn: '''Ooo, Shmowing, that sounds kinda math!

'''Peppermint Butler: '''Shh! Don't say it out loud! Now, look, Finn, if Jake starts acting... cuckoo, call me with your... you know what.

'''Finn: '''[confused] Thaaanks?

Inside, Jake sits on the couch, munching on some chocolates. He grabs his cell phone to call Lady Rainicorn.

'''Jake: '''[''with phone up to his ear, realizing there's no cell service''] Hmm. Guess I can't check on Lady and the Pups...

'''Jake: '''[''grabs for chocolates''] Hmm. All out, I guess. Oh, well.

'''BMO: '''Jake, are you upset?

'''Jake: '''Of course not!

'''BMO''': Good.

'''Jake: '''[crazy] I'LL RIP YOUR CIRCUTS OUT THEN PUT THEM BACK IN THROUGH THE HOLE I CUT THROUGH YOUR FACE!

'''BMO: '''AAAAAH!

'''Finn: '''Jake, you're scaring BMO! Go calm down, dude.

Jake sits in the bathroom on the toilet.

[''a ghostly LSP appears in front of Jake'']

'''LSP: '''Oh my lumping Glob, what're you pouting about?

'''Jake: '''LSP... let me use your phone to call Lady!

'''LSP: '''No. Not unless you totally disembowl Finn and BMO or somethin' like that.

'''Jake: '''Why should I do that?

'''LSP: '''Uh... they'd be, like, really grateful if you did it, and... JUST FLIPPIN' DO IT, ALRIGHT?

'''Jake: '''Okay...

Finn walks into a darkened room calling for Jake.

'''Finn: '''Jake? Jake? Calmed down yet? [''notices typewriter''] What this? He's writing a book? [''reads it''] "All boringness and no fun make Jake angry". Whoa! That's not what I was hoping for...

[''lightning strikes, revealing Jake standing in the back of the room'']

'''Jake:''' Hello, brother...

'''Finn: '''Ready to apologize to BMO?

'''Jake: '''What do you think, Finn? Do I look like I'm ready to apologize, or do I look like I'm ready to... what's the word?

'''Finn: '''[''kind of creeped out''] Attack me and BMO in a murderous rage?

'''Jake: '''That's it!

Jake stretches into random shapes and sizes, then turns back to normal and chases Finn. Finn runs over to his backpack, and grabs his sword, pointing it at Jake.

'''Jake:''' [backing Finn slowly up some stairs] Put the sword down, Finn. You wouldn't slash your BRO, would you? I thought you were more, well, HEROIC then that!

Finn swings off his backpack and hits Jake in the head with it, knocking him out. He picks up Jake and carries his body into a cold shed behind the castle, leaving him there with a bunch of weapons.

'''Finn: '''Should I leave him here with all these axes and daggers? Well, the worst he can do is get the blades of e'm all covered up with his smudgey fingerprints...

Finn exits the shed.

Inside the house, Finn and BMO sit around peacefully eating dinner. Outside the

door, Jake chops his way in with an axe.

[''Jake chops through door'']

'''Jake: '''Heeeere's Jakey!

'''Finn and BMO: '''Aah!

The 2 run out through the other door, being chased by Jake. As they run, Finn remembers something important.

'''Finn: '''Don't worry, BMO. I can use my... [''whispering''] "Shmowing"... to call Peppermint Butler. [''concentrates'']

[''Peppermint Butler is dusting off some statues'']

'''Peppermint Butler: '''Uh oh. Finn and his talking video game are in trouble!

[''He runs out of the room so fast that his cell phone goes flying out of his back pocket and through the open window'']

'''Peppermint Butler: '''Pep But's coming to the rescue! [''walks into hallway''] All right, stretchy mutt... bring it on!

[''Jake runs up and kicks him in the back, knocking him out'']

'''Finn:''' Oh, crud.

Jake walks towards them menacingly with the axe. They run outside into the snow, but Jake stretches forward to catch up with them.

As he raises the axe high above his head to chop, he suddenly notices Peppermint Butler's phone in the snow.

'''Jake: '''YESSSS! [''drops axe and grabs phone'']

'''Jake: '''[''talking on phone to Lady''] Lady! Girlfriend, mother of my pups, [''sad''] person who I miss. [''all lovey dovey and mushy''] Don't be sad, Lady, I'm coming home soon... okay, bye. [''Jake hangs up and suddenly notices some chocolates lying on the ground''] This is the best day ever!

[''Finn and BMO sigh'']

[''End of segment one'']

Finn is unimpressed.

LSP and Cinnamon Bun enter the room.

'''LSP: '''Oh my glob, scary stories!

'''FINN: '''You two are just in time for this story, which I call...
