Thundarr the Barbarian (1980)

S2E3 Island of the Body Snatchers

The trio explores an area known as the Mystery Zone, where numerous ships have met their demise on a mysterious island. They discover that the malevolent witch Circe is behind the wrecks, seeking a young sorceress to break a curse that keeps her trapped in her stone form unless she stays on the island. When Ariel arrives alongside Thundarr and Ookla, Circe seizes her chance, swapping bodies with Ariel. This nefarious switch poses a significant danger to the group as Circe attempts to escape the island.
