Monster Tails is an animated segment on Wake, Rattle & Roll. It is about a group of pets who live in a castle in Transylvania with their guardian Igor Jr. (voiced by Charlie Adler), the son of Igor (Iggy for short). They had similar personalities to their masters, who are in Hollywood making movies.
- Frankenmutt (voiced by Frank Welker): He is the dog of Frankenstein's Monster. He has incredible strength, organ-playing abilities and the brain of a genius, literally.
- Elsa (voiced by Pat Musick): She is the pet dog of the Bride of Frankenstein. Elsa has the brain of a parrot and a crush on Frankenmutt.
- Catula (voiced by Charlie Adler): He is Count Dracula's cat. Although arrogant, Catula is a master of magic and transformations, usually.
- Mumfrey (voiced by Frank Welker impersonating Woody Allen): He's the Mummy's dog. Mumfrey is a constant insomniac.
- Dr. Veenie (voiced by Jonathan Winters): He is a brilliant scientist like his master, Dr. Jekyll. But whenever he sneezes, he transforms into the superstrong but berserk Mr. Snyde (who is like Dr. Jekyll's alter ego, Mr. Hyde).
- Angel (voiced by Pat Musick): The pet goldfish of the Creature from the Black Lagoon. Angel is a ghost because she was eaten by a shark. Angel tends to shout at certain times.
