grey, rhinoceros-like beast of Africa, the horn of the Erumpent contains a violently explosive fluid. Anything touched by that fluid will explode, including other Erumpents, a fact which renders this species quite rare. Erumpents possess a thick, charm-repellent hide and a long tail, rope-like in appearance. Female Erumpents give birth to one calf at a time and the Erumpent's horn, tail and fluid are used as potion ingredients
