The Mermaids are mythical sea creatures from Welcome To The Bikini Bottom Triangle. It appears that there are 5 mermaids like Mindy (King Neptune's Daughter). They first appeared as antagonists, as they stole many objects from Bikini Bottom without really caring about the people. When they sung their song backwards, it returned the enormous pile of stolen objects to Bikini Bottom. They decided to go to the Bikini Bottom with Pearl when she shows them what a mall is (even though they had no money). Patrick had a crush on the mythical Mermaids. Unlike Mindy, the mermaids looked hated seeing Patrick when he was going to "hang" with them for a while.
