Meap's species

Meep is an alien on Phineas and Ferb. He is first seen crashing his UFO into Phineas and Ferb's backyard. They befriend Meep, and try to help him. Phineas, Ferb, and Isabella are later taken to a prison for alien species. They find someone wearing a mustache, and Meep takes it off, and wears it, and starts talking. He briefly appears in the Phineas and Ferb Christmas Special, recieving a frame with a picture of Phineas, Ferb, and Candace in it from Santa.
