Mitch

Mitch, who allegedly also goes by Big Mitch, is Meap's nemesis. He owns a space station. Mitch poaches animals from their homeworlds and keeps them caged up in his space station. Phineas, Ferb, Isabella, Candace, Heinz Doofenshmirtz, Perry the Platypus, and Meap are the only ones who know that the space station exists. Mitch often wears a universal mustache translator.

Finding Balloony
Heinz Doofenshmirtz, when he was a kid, painted a face of a balloon, sprayed it with life-long lasting spray, and named it Balloony. One day, though, while he was protecting the Doofenshmirtz family's garden, Balloony floated away. Later, Mitch found Balloony floating in space and named him Colin.
