(lightening cracks) (dramatic music)
- This stinks.
Hey, how much longer until we get to the mysterious party?
- Let me check the spooky invite
sent to us by our anonymous host.
Oh, we're here. Party's in that castle.
(lightening cracks)
(gentle music)
It's for us.
- What's it say?
- Wear me.
- [Both] Wear me?
(both whistling)
- [Finn] Hello?
- Yoo hoo. Hey guys.
- Princess Bubble Gum. Is that you?
- Why yes indeed.
Although, according to the invitation,
we're supposed to use mystery names
and mine is Lady Quiet Bottom.
- My name is Duchess Gummy Buns.
- [BMO] I am Professor Pinch.
- I'm Cinnamon Bun.
- What's the name on your invite?
- Oh yeah.
Oh, it's Guy Farting.
- Prince Hop On at your service.
- I'm Randy Butter Nubs.
- So who's our host anyways?
- Nobody knows.
- Maybe he'll be a steaming hot babe with huge money.
- Tut-tut Lumpy Space Princess,
what would your boyfriend Brad say?
- Brad and I broke up a long time ago, duh.
- Now's my chance.
- No way.
- But I can make you happy.
- Get up your big donut.
- Okay.
- Excuse me, Guy Farting. There's an envelope on your back.
- Where? Where?
- Here. Let me.
- Did you put that envelope on him?
- No. - I didn't do it.
- What's it say, Prince Hot Bod.
- Esteemed guests. I am your host.
I am a ghost.
(all gasping)
By the time you finish reading this,
I will possess one of you
and use your body to murder every one in the house.
(all gasping)
- We gotta get outta here.
- CB, wait.
It says anyone who tries to leave will die.
- No, no, no, no, no, no, no.
(thunder roars)
- Yeah right.
- What do you mean yeah right?
- Come on.
You don't remember
when I pulled this same trick on your birthday.
I used the fake skeletons
to make you think everyone was dead.
- It looks real to me.
- Classic move.
- Dude, I swear I'm not pranking you.
Cinnamon bun is dead.
The question is who killed him?
One of us is possessed by a murderer
and if we wanna stay alive,
we have to figure out who's hiding a ghost
inside their mortal body.
BMO, use ghost detecting equipment to screen everyone.
- I blinked my balls, my eyeballs.
(Princess giggles)
- Hmm.
- What do you mean hmm?
- Nothing.
- [Lumpy] I knew it was Jay.
- Processing data.
- So who's the ghost, BMO?
- Oh, I don't have ghost detecting equipment.
I just like taking nice pictures.
- Let's find some candles.
If the lights go out again,
we'll be able to catch the murderer.
- Good idea.
Jake and BMO, you guys check downstairs
and we'll take this floor.
- Okay.
- Lay the truth on me, BMO.
Is Finn pulling some elaborate prank on me?
- No, Jake, when bad things happen,
I know you want to believe they are a joke,
but sometimes, life is a scary and dark.
That is why we must find the light. A-ha! Found it.
- Ooo. hahaha
Thanks, BMO.
BMO?
- Help.
Jake, help.
- BMO.
- Help.
(Jake screams)
- Oh my crease, oh my crease.
Assemble. Reassemble.
Come on, you guys.
- Where's BMO?
- The ghost got him.
- Don't you mean you got him, ghost?
- You guys, if there really is a ghost killer,
then we should stay in a group.
He can't take us all on if we're in a group.
(Lumpy screams)
LSP, where are you?
Are you okay?
- It sounds like she's in there.
- I'm dying.
Ah gross.
My lumpy body's all hollow now.
I gotta put something in it,
so where's the food.
What kind of castle is this?
It's like a poor people's castle
with no lumpy waffles for my dump truck.
Chill out, girl.
