Belle (Mermaid)

A mermaid that looks like Belle from Disney's Beauty and the Beast as a mermaid makes a cameo during the scene "Accidentally in Love" in Thomas and Tillie, when Thomas and Tillie are on the beach during their honeymoon.

Thomas and Tillie
A wave comes in and washes up this mermaid, leaving her on top of Thomas, kissing him. Soon after, Tillie throws her back into the sea, where it is implied that she is attacked by two sharks (though it is not certain whether she is eaten or merely attacked).
