We all remember the spin-off forum on TV.com, right? While some ideas weren't generally pleasant or seemed rather redundant, I think we can all agree it did have potential. So, come on, unload your crazy fanboy/girl mind on the spin-offs you know you always have thought about.

I'll start:

You all remember "Phineas and Ferb Take the Future!" right? "After accidentally stumbling into a time rip, Phineas, Ferb, and Perry enter the year 3020 A.D! An awesome thing for the boys, they move in with the elderly Professor Galen as his apprentices, and they take to the future quickly. And, meanwhile, Perry meets with the future of the agency and fights new villains, including a clone of Dr. D!"

I'll start reposting and posting the episodes when this picks up!

On the very last episode of Phineas and Ferb, Perry gets busted. The result is something similar to his nightmare in "Phineas and Ferb get Busted" and he gets relocated. The boys, of course, think it's totally cool that they had a secret agent for a pet and never even knew it! With new owners in a faraway place, and a new nemisis, he gets his own series, "The Adventures of Perry the Platypus, aka Agent P!"

Hm, sounds cool.

You could possibly do a spinoff.......a mini series based off of the adventures of Perry the Platypus, since, according to what I have been hearing and reading lately, his segments are the most popular to watch.
