Winnie Megan Werewolf (simply known as Winnie) is a supporting character in Hotel Transylvania, and a major character in Hotel Transylvania 2 and Hotel Transylvania 3: Summer Vacation. In the original film, she was usually seen with a binky in her mouth and is one of the werewolf pups. In the second and third films, she is not seen with her binky anymore, as she has already grown up by the time of the sequels. She is apparently the youngest and the only one who respects Wayne.
She is voiced by Sadie Sandler, the firstborn daughter of Adam Sandler, who voices Dracula in the film series and currently Zoe Berri.
