In this sequel to the clever "Monster-Mash", the story spans about five years, from Drac's daughter getting married to a human man and having a red-headed kid. Then, they are all waiting to see if that boy will be a human or a vampire. While the parents say it's fine if he's human, this doesn't sit well with the Count, who is constantly taking him out and testing him.
It all comes to a head when a group of troublesome werewolves cause problems-and they all get their answer if this kid has supernatural abilities. Part 2 is about 20% as good as the first, so don't bother to see it.
