Breedz
Each Petz breed has its own body shape and color variations.
Catz and Dogz 1 began with 5 Breedz per game. Petz 2, 3 and 4 contain 10 Breedz per game, referred to as the Original PF Magic Breedz. In addition to what became 10 Breedz, avid Petz fans began using a hex editor to modify the 10 Breedz to form new ones. This hexing continued through Petz 3 as well. Petz 5 saw the addition of 5 new Breedz per game, referred to as the UbiSoft Breedz.
