Yes. In the fourth season, Beijing Opera cats are happy. They want to drink candy because they are willing to play, and they are happy to catch candy to play with them. Sugar is willing to be a prisoner. Tangtang and Huanhuan are the characters in the Beijing Opera Cat, so the relationship is between the characters in the same play, not hostile. The story takes place in a country called "Cat Land". Cats are the spirit of all things, but there is a kind of black smoke called "Chaos" on the cat land. Chaos will attack cats actively and turn them into unconscious and aggressive monsters.
