Goosio was a character who appeared in a host segment in episode 1008, Final Justice.
In one of the episode's theater segments, Mike pointed to a parade float and said "It's the beloved Maltese children's character Goosio!" In a subsequent host segment, Goosio, friend to Maltese children everywhere, appeared on the Satellite of Love as a goodwill ambassador. Crow and Servo assumed that Goosio was a lifeless puppet that Mike was using to play a joke on them and proceeded to savagely attack and kill Goosio, much to Mike's dismay.
