I love both shows, but that doesn't mean they should meet. Their styles are completely different, artistically, tonally, and story-form-wise. There might be some way to make it work, as with the Jimmy Timmy Power Hours, but there are also so many ways it could go horribly, horribly wrong. They're also from different networks, so the chances of it happening smoothly are next to nil.

It's one of the more plausible crossovers I've heard suggested, though. The P&F crew do things like hop dimensions a lot, and I could see Dipper thinking Phineas' head was some sort of supernatural deformity. lol

it be cool. its like Mabel and dipper find this portal and it sucks them into phineas and ferbs world. so dipper has this whole rivalry with baljeet and Mabel meets Isabella and they become best friends so Mabel and Isabella have this talk about Isabelle's crush on phineas and Mabel tells her to tell him cause he might leave someday (like all of Mabel's "boyfriends") so Isabelle finally tells phineas about it and the feeling is neutral and they become a couple. so meanwhile baljeet and dipper have this whole fight to see who's smarter and they both can't answer a question and they just agree to get along and it turns out Buford knows the answer and they are both shocked. so in the end Mabel and dipper go back to there world and Isabelle thanks Mabel and and says she will never forget her so Perry comes back and phineas and Isabelle holding hands say there you are Perry, look at each other and smile, there you are

I don't like Phineas and Ferb that much but I'll watch it.

It would be really funny if Bill showed up.
