The Werewolf Kids are the children of Wayne and Wanda. With the exception of Winnie, they are a rowdy and ill-behaved bunch. Most of them appear to be male, but it is unknown just how many of them there are.

Since they never stay in one place for long, it's hard to know just how many werewolf pups Wayne and Wanda have whelped: one estimate was fifty-nine, but directorGenndy Tartakovsky would only say "there are more than twenty but less than one hundred." Even if Wayne has lost count of his brood, the pups' effect on the hotel is hard to ignore as they mark their territory in more ways thanDracula can tolerate. "The disorder they cause in the hotel provides the audience with insight into how uncomfortable Dracula gets when he loses control over something," says head of story Kaan Kalyon. His obvious disapproval regarding Wayne and Wanda's parenting style is a peek into Dracula's belief that he has done right by Mavis, preventing chaos by keeping her more leashed than these whirling fur-balls of frenzy.
