[ wind gusts ]
This stanks.
Hey, how much longer 'til 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.
[ thunder crashes ]
It's for us!
What's it say?
"Wear me."
BOTH: "Wear me"?
[ both whistle ]
Hello?
BUBBLEGUM: Yoo-hoo!
Hey, guys!
Princess Bubblegum, 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 Gummybuns."
-I am "Professor Pants." -I'm "Cinnamon Bun."
What's the name on your invite?
Oh, yeah.
Uh, it's "Guy Farting."
"Prince Hotbod" at your service.
I'm "Randy Butternubs."
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!
[ all gasp ]
Now's my chance!
No... way!
But I can make you happy.
Puke off, you big doughnut!
Okay.
Excuse me, "Guy Farting,"
there's an envelope on your back.
[ grunting ] Where? Where?
Here -- let me.
Did you put that envelope on him?
-No. Nope. - Unh-unh.
I didn't do it. No.
What's it say, "Prince Hotbod"?
[ clears throat ]
"Esteemed Guests, I am your host.
I am a ghost."
[ all gasp ]
"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 gasp ]
Aah! We got to get out of here!
FINN: C.B., wait.
It says anyone who tries to leave will die!
No, no, no, no, no, no, no!
Ergh!
[ thunder crashes ]
[ all scream ]
He's dead!
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.
Psh! 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 want to stay alive,
we have to figure out who's hiding a ghost
inside their mortal body.
Beemo! - Aah!
Use your ghost-detecting equipment to screen everyone.
[ high-pitched whining ]
[ camera shutter clicks ]
I blinked my balls -- my eyeballs.
[ camera shutter clicks ]
[ giggles ]
[ camera shutter clicks ]
Hmm.
What do you mean, "Hmm"?
Nothing.
Did you just see that?
Oh, I knew it.
I knew it was Jake.
Processing data...
- Ew. - Huh?
So, who's the ghost, Beemo?
Oh.
Um, 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 Beemo, you guys check downstairs,
and we'll take this floor.
Okay.
[ thunder rumbles ]
JAKE: Lay truth on me, Beemo.
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 scary and dark.
That is why we must find the light.
Aha! [ crack ]
Found it! -Ooh!
[ chuckles ]
Thanks, Beemo.
Beemo?
Help!
Jake, help!
Beemo?
Help!
Aaaaaaaaaah!
Oh, my crease! Ohhh, my crease!
Assemble!
Reassemble!
Come on, you guys!
Where's Beemo?
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.
[ screaming in distance ]
LSP, where are you?!
Are you okay?
It sounds like she's in there.
LSP: Aah! I'm dying!
[ toilet flushes ]
Whew!
Oh, gross. Ugh!
My Lumping body's all hollow now.
I got to 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 lumping waffles for my dump truck!
Chill out, girl.
You find any candles upstairs?
No.
Well, I dropped a lighter downstairs,
but there's no way I'm going back for that.
Uh-huh.
Let me remind y'all that the invite says
"The ghost will possess one of our bods."
LSP: Not my bod.
Someone at this table isn't who they appear to be.
That's right... "Jake."
So let me ask you a question only the real Jake could answer.
Who is always next to me
in my recurring elevator dreams?
A half-orc Shaman.
Okay, you're Jake.
So, who else was absent when Beemo got nabbed?
Oh, yeah, right.
I'm not the ghost. I was in the potty house.
A convenient alibi.
But tell me this...
Why did you break up with Brad?
Only the real LSP would know that.
Pshaw! As if you even know the answer to that, Jake!
You're right, I'm just feeling gossipy,
and I want to know what happened.
That's none of your lumping business!
Sounds suspicious.
I bet you're the ghost!
She did it! She's possessed!
Tie her up!
Oh, she is, huh?
Well, before we tie up LSP, answer me this...
LSP: Brad -- He kissed me on the mouth,
and I was like, "Bleh! Bleh! Bleh!"
And then I was like, "Oh, gross! Go away, Brad!"
And he was like, "Obvi, you're not ready for me."
But what does that even mean, you guys?
[ sobs ] What does it lumping mean?
[ whimpers ]
But answer me this, Princess...
What do you want from me, Brad?!
You said I was the hottest one!
Isn't that enough?! Why'd you have to --
[ sobbing ]
What did I write to you on your "Happy Birthday" card
two years ago -- word for word.
Finn, there's no way I would remember that.
I remember that.
You're not PB! Tie you up!
[ gasps ]
What?! Wait, you guys!
[ gasps ] Look!
[ wails ]
A real ghost?!
Aah! Don't touch me! Don't touch me!
[ hollow thud ]
Da-a-a-a-a-a-g!
This wasn't supposed to h-h-happen!
Aha!
I knew you were pranking me back, you!
Yeah, i-it was all a setup --
the doors, Cinnamon Bun and Beemo.
Oh, Striz!
Beemo and Cinnamon Bun should be in the closet over there.
Guys! Guys, guys!
Come on, you gu-- Aaaaaaah!
Aaaaaaaaaaaaah!
Oh, my Glob!
I can't take this, you guys.
I'm calling my lumping parents right now.
[ thunk! ]
Aaaaah! Aaaaaaaaaah!
FINN: LSP, what's happening?!
Aaaaah!
Oh, my glob! I'm not ready!
Get away!
Oh, gross!
Aaaaaaah!
Where did she go?!
Look!
I'm scared, Bro.
[ evil laughter ]
Run, homey! Run!
FINN: Open it!
[ grunts ]
It won't open!
Muh! Aah!
Whoooooo!
BOTH: Aaaaah!
Oof!
-Come on! -Okay.
Oh! Jake!
Ow! Ow! Ow!
I got a splinter!
Jakey!
Whaaa!
Don't let go, man!
FINN: Oh, no!
Your fancy glo-o-o-o-ves!
Aaaaaaah!
[ plop! ]
Unh!
Jake!
Princess!
[ warbling ]
Ugh!
Unh!
[ crows squawking ]
[ panting ]
Yaaaaaaaaaaaaaah!
Ha-haaa!
Gotcha, dude!
Two for two.
What?!
I figured out your plan months ago,
so I flipped the script.
Oh, yeah!
So everyone's okay -- Beemo, Cinnamon Bun?
- Yeah. See? - Whoa! Sick!
You can phase people into your body?
[ speaking Korean ]
I'm ready for you now, Brad.
Isn't that Obvi?
I'm so ready.
But, PB, you melted.
It was a wax dummy, Dummy.
Jake switched me out while lady was distracting you.
Wow. You got me again.
I can't believe that --
With the hair and the house coming alive and stuff.
The what?
The walls and chairs trying to eat me and stuff.
Eh, no.
You must have been so scared, you imagined that part.
Um...no, I didn't.
Ha ha. Nice try, Finn.
Let's get out of here.
[ warbling ]
That one's going in the vault.
And...
It's gone.
