User blog comment:Psychopulse/Phineas and Ferb continues to expand, and a possible spin off involving the Fireside Girls.../@comment-2156322-20100706164953

The creators have said they will not place them in school, but I wonder if we could have a Phineas and Ferb spinoff when they are about 5 years old so we can see what Isabella was at that age since we never have seen her when she was younger (but a backstory about Phineas, Ferb and Isabella how they met would be good as well). As for the Fireside Girls spinoff, I don't know what they would do about the C-plot, but maybe a teenage family member member of a girl (e.g., Gretchen)tries to bust them, but Poofenplotz makes it disappear just before that character's mom is going to bust the troop. Thoughts?
