A platypus represented a species capable of sentient thought, characterized by its teal colored fur, a bill resembling that of a duck, a flat, orange-hued tail, and feet equipped with webbing. Its method of communication involved producing a consistent clicking sound using its mouth. Their eyes could manifest as brown. The agent named Perry from the Alliance to Restore the Republic belonged to this species.
The platypus made its debut in Phineas and Ferb: Star Wars, a television special considered non-canon. Its design draws inspiration from the actual mammal, the platypus, taking particular cues from the platypus as depicted in the television show Phineas and Ferb.
