Gravity Falls, Season 2

"Blendin":
Look, maybe it's against the rules, but you once did a favor for me, so I thought I could help you out! It's called a Time Bubble. It prevents time from going forward. Summer in Gravity Falls can last as long as you want it to!

Mabel:
R-really? But how does it work?

"Blendin":
I-I just need you to get a little gizmo for me from your uncle. (shows the rift) Something small; he won't even know it's missing.

Mabel:
Huh...Maybe Dipper has something like that in his nerd bag. (takes out the rift) Huh, that's...odd. Is this it?

"Blendin":
Yes, that's it! Just hand it over and I'll do my thing...unless you're ready to leave Gravity Falls?

Mabel:
(wistfully) Just a little more summer...(hands over the rift)

"Blendin":
OOPS! (drops the rift and smashes it with his boot)

Mabel:
What?!

(Blendin cackles, taking off his goggles to show he is possessed by Bill Cipher)

Mabel:
Oh, no! Wait, wait, wait!

(Bill snaps his fingers, knocking Mabel out. Cackling, he emerges from Blendin's body)

Bill:
At last! At long, long last! The gate between worlds has opened! The event one billion years prophesied has come to pass! The day has come! THE WORLD IS FINALLY MINE!
