Hotel Transylvania: The Series - "The Song Remains Asleep"
Count Dracula must still remain on the Vampire Council, but while he’s away, he’s managed to harness crystal ball technology to talk to and keep tabs on Mavis at Hotel Transylvania. But that doesn’t mean she can’t spread her bat wings and begin to experiment with and explore her newfound powers and abilities. Now that she’s had her Fangceanera and received her cape, Mavis is on her way to becoming a force to be reckoned with in the underworld.
