Grumbletooth
Grumbletooth is a goblin who makes his home under the stairs or in the cellar of old houses. He is known for his bad temper and his love of riddles: he will sometimes help—or hinder—humans who answer his questions correctly. Get one wrong and he may hide your keys or sour the milk.
Habits and Lore
He is described as small, gnarled, with a prominent jaw and a voice like grinding stones. He dislikes loud noise and disrespect; offerings of bread and honey are said to keep him calm. See “Grumbletooth's Riddle” for a tale. For more on goblin kinds, see Glossary.
