J.P. Ghastly

J.P. Ghastly is a student at Gravedale High. His monster classification is unknown, although he appears to be a blue-skinned gnome. He has a lot of money, and as such seems to attract the attention of female monsters, in particular Blanche. He appears to be based off Peter Lorre and Marty Feldman in their "Igor" roles of creepy assistant to the mad scientist.
