Erumpent

The Erumpent is a huge African magical beast resembling a rhinoceros. It is a powerful creature, with a thick hide capable of repelling most curses and charms, a single long horn, and a thick tail. They are treated with great caution and respect by African wizards and witches.

The Erumpent will not attack unless provoked, but the results are usually fatal. The horn can pierce skin and metal, and the horn contains a deadly fluid< which causes whatever is injected with it to explode. There are apparently rare occasions when the injected object or being does not explode, as in the case of Wilfred Elphick, first wizard to be gored by an Erumpent. As his Chocolate Frog Card depicts him in bandages, but very much alive, it can be assumed that he survived the attack and did not explode.

Erumpent numbers are not large, because male Erumpents frequently blow themselves up during mating season. Erumpents only give birth to one calf at a time.

Erumpent horns, tails, and Exploding Fluid are all widely used in potions, although they are listed as Class B Tradeable Materials.
