Revenge of Madzilla's Mom

Revenge of Madzilla's Mom is a monster movie that was assumedly filmed in Hollywood at some point.

The movie was only briefly mentioned in The Adventures of Super Mario Bros. 3 episode "Dadzilla", while Mario, Luigi, Toad, and Princess Toadstool were locked in the props garage. Mario found the head of Madzilla's mother in it, and Luigi recognized it from the aforementioned movie.

Not much else is known about the movie, though the "Revenge" part of the title suggests that it is a sequel to another "Madzilla's Mom" movie.
