He is an oddball among the mouse community from birth, as he is born with a small body, huge ears, and open eyes. He grows up to be very different from the other mice in this tale, choosing to read books instead of eating them not being afraid and letting humans see and talk to him. This behavior is noticed and he is punished and sent to the dungeon. Despereaux must rely on his wits, bravery, and inner strength in order to save himself and the princess.
