How do cats and mice choose their own skin when customizing their rooms?

Cats and mice can customize the room and choose their own skin, as shown below:

1, the cat-and-mouse mobile game was updated on April 24th. After this update, a custom room ban mode and a contest quiz have been added.

2. There is team skin in the activity. Click in and you can team up with the trumpet, so that all sizes have skin.
