Beaver

A beaver is a type of semi-aquatic rodent known for building dams. It features a large pair of teeth that are excellent for gnawing.

Rubeus Hagrid was known to sometimes wear enormous boots that were made of beaverskin.

In 1994, the accidental use of the Tooth-Growing Spell on Hermione Granger caused her teeth to grow to a point that she looked like a beaver.
