Mushroom Mob

Well, you should update mushroom biome my idea Is: to out like mushroom creeper, zombie mushroom, or Creeper Mushroom for example make themed mobs, like zombies turn red and change their shirt as soon as they enter the mushroom biome, and mushrooms sprout on their head, endermans turn red, and creeper become Brown, with Brown mushroom in their head, i think this Is a good idea, bye!
