Hey everyone! I just heard from the Dan Povenmire and Jeff "Swampy" Marsh that Phineas and Ferb is doing so well that they're making two spinoffs to this cartoon! The first one is Adventures of Agent P, an expanded series revolving around Perry the Platypus stopping Dr. Doofenshmirtz from taking over the Tri State-area. The second one doesn't have a lot of info, but it's basically revolving around Isabella and the Fireside Girls. Here's the link to the info.
