Naturally-bred Personality Swap Petz
One thing I've always found fun in Petz is when Petz have the face of one breed but the personality of another. Like that funny grumpy alley face with a prissy chinchi personality. I started trying to breed for this and discovered some interesting things. Personality is tied to scales (thanks Shaina @ Kizmet), which is a value in a breed that determines sizing. You can't do a swap if the breed has the same scales in Petz 4. So you can't naturally breed a Alley face with a Calico personaity (even if it says Calico in GenePoolz) because both breeds have scales of 110. But you can in Petz 5 for some reason.
