The kids of The Addams Family had an array of strange pets in their house over the years, but none were as slimy or bizarre as Aristotle, Pugsley’s pet octopus. Whenever it was shown on screen, it was very obviously made of plastic, yet it still managed to creep kids out. And as if the family wasn't weird enough, Morticia and Gomez were often seen in their backyard giving Aristotle baths in the middle of the day. We’re not sure what that does to the property value of the house, but it can’t be good for their neighbors.
