Screwsnail

A freak skeleton who winds the clock on the second floor. He is always slow.

Description
Most adorable of all the school skeletons is their handyman, Screwsnail, who almost looks like something out of a Bosch painting with his long, spiny bird-rodent snout and heavy snail's shell. His shell can store a seemingly endless supply of tools and spare parts, and naturally weighs several tons.
