Amy is a crystal mermaid Velma meets in Crystal Cove Bay. She later visits her at her house to alert her that Skipper Shelton and his brother were taken by Fish Freaks. Finally Amy sings to lead the monsters into a trap that Daphne captures them in with the words "Too bad, ya suckers, now you're caught in my net!" Amy is voiced by Tia Careere, same person from Aloha Scooby-Doo.
