In the Monster Club there is only one Humgoo, and her name is Una. On the Monster’s Genealogical chart Humgoo is spelled Humegoo, but in the movie credits and IMDB it is spelled Humgoo. I mistakenly thought the first 100 or so times I watched the movie that everyone in the village in the third story were Humgoos, when in reality they are ghouls. Only Una, the daughter of the innkeeper, is a Humgoo.
