Adventure Time, Season 7

Prismo:
Thanks for responding to my call, guys. I'm in a serious pickle, and I mean the bad kind—I mean like, a really smelly brown pickle?

Jake:
Don't sweat it, boi! Finn and I got your back.

Finn:
Who's bullying you, Prismo?

Prismo:
Nobody's bullying me. Look, um... remember when you wished the Lich never existed and you created a new wish reality that ended up totally not working out?

Both:
No. / Vaguely, yes.

Finn:
What?

Jake:
You don't remember making that wish?

Finn:
Wha..?

Jake:
I thought I explained to you that one time.

Prismo:
Dude, I'll catch you up. Look. [turns on TV wall to see alternate Finn and Jake playing the flute and howling, respectively] After you wished the Lich never existed, you got zapped to an alternate wish reality where magic doesn't really exist.

Finn:
Wait! [pause video] Who's that dude?

Prismo:
That's you, but sort of less cool.

Finn:
..Uh-huh. Proceed.

Prismo:
So, you find an old Marceline and the magic crown on the body of Ice King's skeleton, who was smushed under the weight of a frozen mutagenic bomb. But then, the Destiny Gang steal your family donkey, so you used the crown to become Ice Finn and save your donkey and your family. But... the crown makes you crazy and you ice everything up like a dumb bozo, which sets off the mutagenic bomb and releases the spirit of the Lich anyway. But then, this reality's Jake made a counter which would supposedly fix the problem, but as it turns out, it didn't really.

Finn:
Can I just say that I don't remember any of this stuff?

Prismo:
Because, technically, it didn't happen to you. But also, it still happened and that wish reality continues to exist.

Finn:
[beat] Is this why all of a sudden one day I was way better at the flute?

Jake:
Oh yeah, I noticed that.

Prismo:
Listen! Something really bad is about to go down. [summons projection] Ice Finn is using his world's Enchiridion to build a portal to the multiverse. We literally do not know what will happen if he succeeds, but it could defs be catastrophic to the architecture of these realities. Now, if that happens, my boss—let me repeat that—my boss will hold me responsible. And by proxy, y'all both will be in the dip, too.

Finn:
Why not just bloop-bloop it all better?

Prismo:
Something there is dampening my powers! I am losing my picks over this biz!!

Jake:
[to Finn] His boss? Who's that?

Finn:
Alright, man. What do we do? [Prismo summons a case to him]

Prismo:
Take this and use it to take care of the Ice Finn.

Finn:
Oh. Wait, what do you mean by "take care of—"?

Prismo:
Good luck, guys! We're all depending on you!
