@Wikidude Well, who knows. Isabella is definitely a popular character, and I for one think that the fireside girl spinoff has potential; especially at the hands of the two guys who made a show about a pair of stepbrothers building stuff in their backyard so exciting. I think the spinoff is meant to target the female demographic. Not that it's needed, as Phineas and Ferb is popular among both genders already.

The spinoff could however be something else entirely. Like a Chronicles of Meap spinoff.
