Fifi

Fifi was the pet Stigorax of Helen A. She was fed on chocolate by Helen for some time. Helen decided she needed some sport and sent her through the underground pipes of Terra Alpha pursuing Ace. Ace set an explosion injuring Fifi. Fifi was returned to Helen and her wounds were treated and bandaged.

Helen then sent Fifi back down the pipes pursuing a number of killjoys, the Doctor and Ace. She was killed when Earl Sigma caused an avalanche the crushed her. She survived for enough time to get out of the pipes were she was found by Helen who wept over her death. (DW: The Happiness Patrol)
