The Ballad of Mavis is the song sung in the Hotel Transylvania: the television series episode, Bad Friday.
Skeleton: It's the ballad of Mavis, the frightner to humans, and the scream heard around the world.
Mavis (speaking): Well, Okay. I went behind a tree, and I saw an open window....
Skeleton: Hidden by The Tree of Decison, with sap of purest gold, Mavis spot The Gateway to Terror! Could she be so bold?
Mavis (speaking): Then I went up to the window....
Skeleton: She Could! She could! She could and she was!
Mavis (speaking): And then I saw Mrs. Cartwright, and....
(Mavis turns into a bat and hisses right at Kitty Cartwright, which caused her to scream.)
Monsters: She scared her prey on Bad Friday! Mavis, frightner to humans!
Mavis (speaking): Um, that's not how it-
Aunt Lydia: I don't think she pulled it off! She's only just a child!
Hank N. Stein: She's scarier than you by far!
Aunt Lydia: Or plain, fast or viled!
Pedro (speaking): She scared the humans and ditched her score, and blasted aliens with a whole bunch of lasers! Oh,you want some of this?! (laughs.)
Monsters: She scared her prey on Bad Friday, and blasted aliens with lasers, hey! Mavis, frightner to humans!
Wendy Blob: Mavis, frightner to humans!
