What is the title of the 1999 animated Scooby-Doo film featuring the Hex Girls?

The 1999 animated Scooby-Doo film featuring the Hex Girls is Scooby-Doo and the Witch’s Ghost.

The film follows Mystery Inc. to Oakhaven, Massachusetts, after the writer Ben Ravencroft asks for help with a haunting connected to his ancestor. The Hex Girls, a fictional eco-goth rock band, perform in the story and become important allies during the investigation.

Scooby-Doo and the Witch’s Ghost was released directly to video in 1999. It followed the success of Scooby-Doo on Zombie Island and continued the franchise’s move toward more atmospheric stories. The film mixes a traditional unmasking-style mystery with a genuinely supernatural element.

The Hex Girls later returned in other Scooby-Doo productions, making them one of the franchise’s most recognizable recurring musical groups. They are sometimes mistakenly associated with Zombie Island, but they do not appear in that earlier 1998 film. Their first appearance is in The Witch’s Ghost.
