Here is a list of things that I think may happen in the season 2 premiere. And remember, not all of them may happen.
- Returning P&F running gags. For example, Milo asking Cavendish and Dakota if "Professor Time" started out as a pharmacist.
- At least one large group of prisoners escaping Lard Word in the first 11 minutes. Either by simply cutting the "bars", or one of the Pistachions forgot to lock the cage(s). "You mean we could've escaped at ANY time?"
- The return of Perry's teammates from The O.W.C.A. Files.
- Melissa's two front teeth being brought up. As a way to decipher which is real, and which is a disguised Pistachion.
- I'm curious to think what would happen if Melissa finds out that Phineas & Ferb are the ones who created the rollercoaster that destroyed her science project.
- Three connected group focused plots. 1) Milo's group with Doofensmirtz, Norm, Perry, Perry's teammates, and possibly Vanessa. 2) Zack and Melissa with Phineas, Ferb, Isabella, Baljeet, and Buford. 3) Sara with Candace, Stacy, and possibly Jeremy.
- Milo could point out that Vanessa sounded like someone he met once before.
- At least on P&F character joking about how they and Danville immune to certain doom for some reason. Referencing the canon future shown in Act Your Age.
- The premiere ending in a reset button. Seeing as the background didn't get destroyed in the original pilot. So the crossover might end in an altered version of the first half of Fungus Among Us.
That's all I could think of. What do you think?
