The Boghog is the only native animal of planet NowWhat, "all other having long ago died of despair". Boghogs are tiny, vicious creatures with unaccountably thin and leaky skins. Boghog meat is almost completely inedible and is the primary source of food for the settlers on NowWhat.

The language of the boghogs consists of biting each other very hard on the thigh and thus was never learned by anybody else.
