ExtraBunnies does two things. The first, is it makes rabbits tameable with carrots (10% chance per carrot) and golden carrots (always tame.)
The second, is that it allows server admins, modpack devs, or players to add custom rabbit textures by placing them in the mod's config folder.
Any custom textures will be synced from the server to the client on join, ensuring there is no texture desync.
