The Seafoam Spirit is an original character from The Land of Stories series, though she is based on the fairy tale character The Little Mermaid by Hans Christian Andersen who falls in love with a human prince and makes a deal with the Sea Witch to trade her voice for a pair of legs in order to join him on land. She needs to make him fall in love with her or perish- when the prince falls in love with someone else, her sisters make a deal with the Seawitch too. The Little Mermaid must kill the prince in order to return to the sea as a mermaid. She refuses and turns into sea foam.
