Montegue - Montegue is an old fashioned monster looking for a girlfiend (yes, fiend) with whom he can share a sundae at an ice cream social. Don't let his stilted way of talking fool you. He is quite well rounded and up to date on movies through the 1970's.
Bloop - Bloop is a distant relative of Mlergh. He has a striped body and a white shirt. He likes baseball and he's very loud.
Mlee - Mlee is part of the League of Lifeguarding Monsters. His specialty is kiddy pools and not the shallow end of the large neighborhood pool - the inflatable kind one might find in a suburban front yard.
Duke - My husband thought that Duke resembled the mascot for Duke University, hence his name. He is quite devilish. Don't let his diminutive appearance fool you.
