Pitz, (Canis fugaraglobus) the dog in Creatures 2, was strongly believed to be a joke played on P.F.Magic, the creators of the "Petz" games, which were a much simpler form of virtual life. The name Pitz would seem to be a dead giveaway. He does not need to eat and makes some noises which are very similar to those of the P.F.Magic Dogz. Pitz can play with the purple tennis ball. The sprites for Pitz feature in the official Object Making Tutorials (Creatures 2).
