Camouflaged Creepers Mod (1.6.5, 1.12.2), adds a special creeper type that alters its skin texture depending on the block it is standing on. It can be spawned in all biomes, except nether, end, and biomes such as ocean, river, and so forth.
This mod adds creepers that can change their colours depending on the environment. This mod alters the Creeper’s default texture to match the texture of the block on which it is standing. It works with almost all Minecraft blocks. This mod can be used even on non-modified servers because it is Client-Only.
