Have creepers stopped scaring you? What if they start creeping up on you completely unnoticed? With this resource pack, creepers will be able to masquerade as cows, sheep, pigs and chickens, completely copying their models. They’ll behave just like any other animal, except they won’t make a sound before they explode.
