Human Jonathan (voiced by Andy Samberg) married the vampire Mephis (voiced by Selena Gomez) and gave birth to a "half-breed" Dennis (voiced by Ash Brinkoff). The hotel rule of "only allowing monsters to enter" was completely sidelined, and the Hotel Transylvania finally opened its doors to humans. But Dennis didn't show any "monster" characteristics, and Dracula (voiced by Adam Sandler) and Mephis also had a disagreement about the baby's education.
After finally tricking Jonathan and Mephis into traveling, Dracula gathers his old friends: Frank the Frankenstein (voiced by Kevin James), Murray the Mummy (voiced by Keegan Michael Key), Werewolf Werewolf En (voiced by Steve Buscemi) and the invisible man Griffin (voiced by David Spade) set up a "monster training camp" for their little grandson, preparing to fully awaken the grandson's vampire bloodline.
Knowing the truth, Mephis and Jonathan went home quickly and finally had a conflict with Dracula. In order to inspire his grandson's vampire genes, he also invited his father, Wallard (voiced by Mel Brooks) to help. But if he is conservative, if he finds that his great-grandson is not a pure-blooded vampire, and humans can now stay in the elf hotel, the world will definitely be in chaos.
As a cartoon suitable for the whole family to watch, the highlight of the film is that it includes the notorious terrifying monster demon characters, but gives it a new image personality and story setting, turning it into a cute and funny cute monster alliance. In particular, Count Dracula, the vampire with brutal temperament and cold temperament, whose gothic dark style has been deeply rooted in the hearts of the people. After the re-interpretation of the film, he retains his arrogant and old-fashioned personality, but more often it becomes a bit of a bitch. A cute father figure who is long-winded and controlling.
