[ Indistinct chatter, laughter, dinging ]
Birthday boy-e-e-e!
Enjoying your party?
It's great having fun with all my friends.
Well, some of my friends -- mostly banana guards.
Yeah, sorry about that.
The Candy Kingdom is in full lockdown
until I can sort out the rumors about my Uncle Gumbald.
He's been gone for years, but we should stay vigilant.
Don't worry, Pb.
Now that I'm 17, I'm feelin' ready for anything.
Feels like I'm really hitting my stride, y'know?
Finn, I want to give you your gift before I forget.
It's a harmonica.
Awesome!
[ Inhales sharply ]
Finn, I designed an exciting new game for you.
Show me.
It's called "Birthday Boyfighter."
[ Game music plays ]
Looks like another hit.
Starchy: Finn, Starchy didn't get you squat.
I got you a present, too.
It has emotional and metaphorical significance.
It's beautifully wrapped.
Wonder what it is?
It's an elk's heart.
Oh, cool. I don't have one of those.
[ Thumping ]
What's that sound?
Starchy: It's zombies.
Sounds like hooves.
[ Galloping intensifies ] Zombie cows.
You're green!
I'm the Green Knight!
And before you ask, yes, of course,
I brought you a birthday present.
It's a battle axe.
That's some axe.
Am I an axe guy though?
I've always thought of myself as a sword guy.
But only if you play me a game for it.
What's the game?
Oh, this game is called "All you have to do
is strike me with it, and it is yours."
Mm?
[ Indistinct murmuring ]
[ Inhales sharply ]
I can't axe some stranger.
Wait a minute! Where's Jake?
I know what's going on.
No, I don't think you do.
Relax, Princess.
Jake loves playing birthday pranks on me.
Yes, of course -- one of Jake's classic pranks.
Okay, I'm in.
[ Clank ]
May your aim be steady.
[ Laughs ] Sure thing...Jake!
[ Clank ]
I win! [ Cheers and applause ]
Yeah, Finn! Yeah, Finn!
Happy birthday, Finn.
[ Scary music plays ] [ Shrieks ]
Jake! When did you -- Whose head did I --
Are you pranking me?
What? No.
My prank is this fake-out gift.
Huh?
What's this guy's deal?
Oh, nuh-uh!
Banana guards, surround him!
And be on the lookout for anything else strange!
Banana guards: Hup, hup, hup, hup, hup, hup, hup, hup, hup!
Surrender, please.
Princess, is that strange?
Yes!
I did good.
[ Screaming ]
My guards!
I got this. [ Shing! ]
Raaahh!!
[ Hisses ]
Eel!
♪♪♪
[ Shing! ]
Get him!
[ Yells ]
[ Groans ]
Aw.
He might have an invisible shield.
But I'm not sure, because it's invisible.
♪♪♪
Owiee.
Yes. It's an invisible shield.
An invisible shield.
I've got a device for the dissolution
of invisible shields.
[ Whirring, beeping ]
[ Fizzles ]
Impossible.
[ Laughs maniacally ]
Heh!
Back off, everyone.
He's using some advanced mystery tech.
[ Laughs maniacally ]
Okay, let's talk.
[ Laughs maniacally ]
What do you want to talk about?
Where did you come from?
Why are you playing this weird game with Finn?
[ Laughs maniacally ]
[ Laughing continues ]
He's playing Mr. Laughing Silent Guy.
[ Laughs ]
Game's over, bro.
[ Laughs ] The game isn't over until I strike you.
Hmm.
Let's come up with a better way to settle this,
like reasonable late teens.
I'm listening.
Well, we've got everything set up for party games.
How about if I beat you two out of three,
you got to answer our questions.
Psst! Nuh!
And if I win... chop, chop. Deal.
Wait, Finn, I think he's plotting something --
I-It's fine. I'm 17. I'm hittin' my stride.
[ Beeps ]
Hey, Green Knight, why are they all mimey?
Ah, just to keep things fair.
[ Clanking ]
[ Sighs ] I don't think he can hear us.
[ Laughs sinisterly ]
Okay, guy.
Why don't we start with something basic
like... balls and coconuts.
Hup! Hup!
Hup, hup, hup, hup, hup, hup, hup.
[ Clank ]
Ba-ba-ba-boom!
Boom!
[ Cheering ] Okay, Finn! Yeah, yeah!
You got it, Finn! You go, boy!
[ Slow-mo ] Boooooooom!
[ Belches in slow-mo ]
[ Tap ]
[ Normal voice ] Aw, what?
I'll let you have that one, 'cause I'm a big boy today.
But let's see you try and beat four out of five, huh?
[ Whirring ]
How do you like them coconuts?
I hate them coconuts.
Something's wrong.
Yeah, I swear that looked fake.
It was.
I saw it all with my Huntress vision.
♪♪♪
Finn is totally getting played.
[ Inhales ] All right.
You got a freaky curveball, man.
But can you climb a greasy pole?
A greasy pole?!
It's hard enough climbing a non-greasy pole!
Ready? [ Chuckles ]
Mm-hmm!
[ Speaks quickly ] One, two, three, go!
[ Grunts ]
Ha, ha!
[ Panting ] [ Slow clapping in distance ]
[ Normal voice ] Huh? [ Slow clap ]
Finn, you climb so good.
I guess you win this round.
Hmm.
Yay, Finn!
Whoo-hoo-hoo-hoo! That's right!
Yay, yay! What, what?
Now's our chance, BMO.
Is -- Is Finn gonna be okay?
He's got this. He's 17.
Who's the ma-a-an?
Who's the 17-year-old ma-a-a-an?
Hoo!
You've been a good sport, so I'll let you
choose the tiebreaker.
[ Muffled ] Don't do it!
Wait, don't do it!
...not a good idea!
Very well. Hmm...
How about a game of some good old-fashioned arm wrestling?
Arm wrestling, huh?
I see what you did there.
My guns are obviously weak as heck
from climbing that greasy pole.
If only I had some kind of...
[ Whirs ] ...superhuman robot arm.
Bam!
Both: Three, two, one, go!
[ Strained grunts ]
[ Strained ] Ahh!
You can't tell from my face, but I am smiling triumphantly.
Nooo!
It's...my...birthday!
I know.
It's my birthday, too.
Fern?
Oh, no! No! Finn!
[ Shing! ]
[ Chuckles ]
Finally, I win!
[ Beeps ] Fern!
We've seen enough.
[ Groans ] Finn! Finn! Finn, are you all right?
Starchy: I love you, Finn!
Quick, eat this elk's heart.
What is this?
It's a family reunion.
Uncle Gumbald, Cousin Chicle, Aunt Lolly.
How are you back?!
Here's a hint --
"Oh, my glob."
Lumpy Space Princess.
[ Woosh ]
When she reset Ooo, she reset...you.
For 800 years, you kept us imprisoned, Princezzin.
No, you were happier as candy people.
We thought we were.
But don't worry...
it's your turn to be happy now.
Get juiced.
[ Hisses ] Back off, gumwad!
The vampire girl is legitimately scary.
Very well.
You've witnessed our superior technology
and watched your champion crushed.
[ Vomits ]
We'll go...for now.
[ Laughs ]
This is my worst B-day ever.
