Cartoon Dimension: Star Versus the Forces of Evil.

"Glossaryck, why are you asking Bill Cipher for help?" Stanford Pines asked him suspiciously.

"When the Time Baby died, Bill Cipher instantly became responsible for correcting any Time Paradoxes that happened afterwards." Glossaryck explained.

"So naturally you Blackmailed Bill Cipher into helping you by allowing him to Leave Gravity Falls unharmed." Stanley Pines says back knowingly.

"I needed Bill Cipher to Protect Star Butterfly and this was my only choice to make that happen!" Glossaryck protested.

Both Stan Twins exchanged worried glances at each other.

"Why is Bill Cipher not Searching Mewni for Star Butterfly right now?" Stanford Pines asked curiously.

"Star Butterfly was kidnapped inside your Earth Dimension by Mina Loveberry." Glossaryck explained.

"I was hopeful that Weirdmageddon would drive Mina Loveberry out of hiding." Glossaryck added thoughtfully.

Both Stan Twins exchanged worried glances at each other again.

"How long can you keep Bill Cipher under your control?" Stanley Pines asked worriedly.

"My deal was Bill Cipher Protecting Star Butterfly in exchange for his freedom." Glossaryck explained.

"So you can Stop Weirdmageddon whenever you want?" Stanford Pines asked hopefully.

"I would need Star Butterfly returned safely, otherwise Humanity will Experience Worldwide Weirdmageddon Forever!" Glossaryck proclaimed.
