Quasimodo Wilson, the former Hunchback of Notre Dame, is now the gourmet chef at Hotel Transylvania. He has a pet rat named Esmeralda and the hidden main antagonist of the film although he's not evil, he's just mean.

He was first seen with Dracula wondering if Jonathan was a human. Dracula claimed that there were no humans around. He complained to Quasimodo that he needed pigs in blankets instead of the dish that was already made. Quasimodo also frequently acted mean against his sidekick, but treated Esmeralda, his pet rat, nicely. The same thing happens when everyone was near the pool.
