There are several skins the player can purchase through the shop with Hazelnuts. Using a different skin from the base one doesn't offer any advantage gameplay-wise. The art for this game, including background, object tiles and character sprites, were drawn by Maharadjah aka DragonChameleon.
|V1.1||Is Your First Skin.|
|Mouse||1200||Depicts a Transformice mouse holding a cannonball.|
While not buy-able in the shop, there does exist a zombie skin in the game, which is used during the zombie powerup.
- The original Bouboum only had two skins, a white and orange cat (orange representing player with highest score). Modern Bouboum also has orange/white cats, possibly as a reference to the original skins.
- In the Transformice edition of Bouboum (which is no longer active), the only skin available was the brown hamster.
