They appeared in episode 101 of The Jim Henson Hour as background characters and later performed by Drew Massey and Victor Yerrid in episode 15 of From the Balcony. One of the puppets was used as Norberta in the home video Things That Fly. The alien puppets have eyes that blink side-to-side. At one point, Palisades Toys considered including a figurine likeness of the aliens in an Accessory Pack for the Pigs in Space Playset. Neither the Accessory Pack nor the figures were ever produced. They appeared in The Muppet Show Comic Book: Pigs in Space.
