The Professor's Peculiarity is a headwear item for the Engineer. It adds graying tousled hair worn in place of the Engineer's hard hat. It also adds a pair of navy blue rimmed glasses with tinted lenses repaired with tape and a paper clip wrapped around the bridge that sits in front of the Engineer's normal goggles.
The hat has two styles, named "Manic" and "Tamed". The Tamed style adds the default hard hat to the hair.
