* In Mad Monster Party?, the giant gorilla "It" (with the vocal effects provided by Allen Swift) is a larger knock-off of King Kong and is most likely named "It" due to copyright reasons. Baron Boris von Frankenstein did not send an invite to "It", since "It" can be a bore and had crushed the Isle of Evil's wild boars the last time "It" was invited, as he explains to his assistant Francesca. Boris has his zombies patrol the island just in case "It" shows up uninvited. When "It" does show up, it goes on a rampage and snatches up the other monsters and Francesca (where "It" develops a crush on her) and climbs the Isle of Evil's tallest mountain. Boris convinces "It" to take him instead of Francesca, which "It" complies to. After Francesca is off the island with Boris' nephew Felix Flanken, Boris sacrifices his life where he drops the vial containing the secret of destruction which destroys himself, "It", the Isle of Evil, and everyone else that was on it at the time.
