The Unknown birds are the doctor's first and best creations. They return to Keep Away Island to eat noodle-worms and play beach-volleyball. They have incredible psychic powers. Their real name can't be spoken in any language and must be expressed as a dance and laser show. Wingus was one of these until Joe started growing on his feet.
- Their major role was in "One Joe Wingus", where Peri and Entrée went with Joe and Wingus to meet them.
- They appear to be vulture mutants with the legs of a stork and the head and tail of a hoopee.
