 In the end, El Clavillazo manages to defeat the monsters, mostly by luck, and rescue the girl.A chemical in Sputnik’s lab devolves the gill-man into a big fish, the werewolf is choked out by the monster in the cell (perhaps that is why he was kept behind bars), Frankenstein accidentally electrocutes himself by grabbing a power cable in the lab and turns into cogs and clock-parts, the mummy falls into a pit of alligators and is devoured, and the vampire vanishes when the sun rises.Dr Sputnik has the usual falling out that all mad scientists seem to eventually have with their deformed assistants (usually due to the scientist mistreating his assistant, or the assistant developing a crush on a girl the scientist has designs on, or sometimes a combination of both), resulting in his being shot after he stabs the scarred hunchback.
