What was the title of the 1998 Scooby-Doo film set on a tropical island?

The 1998 film set on a tropical island was Scooby-Doo on Zombie Island.

The direct-to-video film follows Mystery Inc. to Moonscar Island, where the group investigates apparently supernatural events. It became especially notable because its werecats and zombies are genuinely supernatural rather than ordinary people using disguises.

The movie was released in 1998 and is widely regarded as a major turning point for Scooby-Doo animation. Its darker atmosphere, serialized-feeling story, and real monsters helped distinguish it from many earlier mystery plots while remaining family-friendly.

Although the title mentions zombies, the film’s central mythology also involves the island’s werecats and a centuries-old curse. It is therefore more than a simple zombie adventure, and it should not be confused with the later film Scooby-Doo! and the Curse of the 13th Ghost.
