Hotel Transylvania has gone through several changes since Johnny first stumbled onto it: the hotel is now open to human guests. Mavis and Johnny have a baby boy named Dennis, whose lack of any vampire abilities worries his grandfather, Dracula. When Mavis and Johnny go on a visit to Johnny’s parents Mike and Linda, Dracula calls his friends Frank, Murray, Wayne, Griffin and Blobbie, to help him put Dennis through a “monster-in-training” boot camp. Later, Dracula’s father, Vlad, unexpectedly visits the hotel and, to his dissatisfaction, finds out that his great-grandson is not a pure-blood vampire and that Hotel Transylvania now accepts humans.

The new movie stars Adam Sandler, Andy Samberg, Selena Gomez, Kevin James, Steve Buscemi, David Spade, Keegan-Michael Key, and Mel Brooks as Vlad.

“Hotel Transylvania 2” hits theaters on September 25.
