Ep 4. Adventures in Vampiresitting / Phlegm Ball

In "Adventures in Vampiresitting," Mavis accidentally turns her Uncle Frank into a baby with a magical potion. While trying to figure out how to reverse the spell, Mavis puts the baby Frank in the care of her best friend, Wendy. But things quickly spiral out of control when Wendy takes the baby out in public and it attracts unwanted attention from a group of humans who mistake Frank for a real baby. Meanwhile, Mavis and Hank try to track down the ingredients for the antidote while dealing with a stubborn gargoyle who refuses to help them.

In "Phlegm Ball," Mavis and Hank team up for the Phlegm Ball tournament, a popular game at Hotel Transylvania where players pass a phlegm ball through a goal using a variety of creative methods. However, their opponents, the notorious Polterguys, will stop at nothing to win the game, even if it means cheating. Mavis and Hank must outsmart the Polterguys and come up with their own winning strategy to take home the trophy. Meanwhile, Pedro tries to impress Esmeralda with his own Phlegm Ball skills, but instead, he ends up causing chaos and havoc throughout the hotel.
