 There is the butler, who looks like the Frankenstein Monster.The rest of the monsters include a werewolf, a mummy, a vampire (clearly modeled after Count Dracula) and a gill-man (clearly patterned after "Creature from the Black Lagoon").There is also another, unidentified monster being kept in a cell (why it is not allowed to run free with the rest is not known), which is referred to as a “gorilla” in some reviews, although it appears to be more of a humanoid ape-like creature, perhaps based on Dr. Jekyll and Mr. Hyde.
