Hop Jack

A Hop Jack is a Ghoul Slug created by using Dark Water on a Hop Rock. At 100 mph, they emit a high pitched screech, become a sickly yellow, with a blue, spiky helmet. They also will have pointed teeth, as well as claws and a spike-clubbed tail. They are commonly used by Dr. Blakk's minions.
