Tomtomme

Appearance
Tomtommes are small blue mice with large horns for ears, and a thin tail with a ball on the end. They have white around their eyes, on their snout, belly, and hands.

Personality
A Tomtomme's tail constantly keeps beat like a metronome, and they are able to make music and all kinds of sounds by using their trumpet-like ears. They are official timekeepers for North of North, and no clock is sold until they have certified it. [1]

Notable Tomtommes
A famous Tomtomme, Tyler Tomtomme, lived on the edge of Darkcomb Woods, and joined a traveling band with Kitty. [2]
