Griffin is one of the many guests that stays in Hotel Transylvania for Mavis' 118th birthday. He is a friend of Dracula and is funny. He is one of the monsters who helps Dracula get to Jonathan, he drives the car. He uses his invisibility to surprise people and to help him during fights. He often seems to forget he's invisible as seen when he expects people to know what colour his hair is, gets embarrassed when his swimming trunks are pulled down and when he shaves and combs his hair while getting ready for the party. He plays drums in the band playing for Mavis.
