Red Sheep, nicknamed "Sheepers", have no official name as of yet. They have the appearance of a sheep dyed red. When hit or the player comes to close too them, they explode with no warning, making them a similar sort of mob to the creeper. Sheepers have been, as of yet, only sighted withing the mob arena. It is suggested that you have the Tank or whomever has the strongst armor/weapon to attempt to kill it in one hit. Should they be unleashed upon the world, nobody knows what damage they could cause.
