The ice cream lady is the frogfish's sentient, anthropomorphic tongue. When she is first seen, she appears to be an elderly, lavender-colored woman with white hair and red cheeks. She wears light blue eyeglasses and a pink shirt with a white collar. It is later revealed that she has no eyes and is connected to the frogfish's mouth.
Role in movie
She is the lure of a carnivorous frogfish. The frogfish uses her to get unsuspecting visitors to enter his mouth, which is hidden under sand and a wooden booth labeled "Ice cream."
In the movie, SpongeBob stops the Patty Wagon at the ice cream lady's stand to buy a snack for himself and Patrick. They do not realize that her stand is surrounded by piles of fish skeletons. SpongeBob orders two orders of ice cream from her, and she hands him what appears to be a bowl. When SpongeBob holds it, it becomes stuck to his hands. It is revealed that the ice cream lady is actually the frogfish's tongue, and that her ice cream is another growth from inside the frogfish. SpongeBob breaks free by biting her arm off, and Patrick saves him with the Patty Wagon. As they drive forward to escape the frogfish, the ice cream lady tries to tempt them with more "ice cream" and promises to let them pet "Mr. Whiskers," a meowing, cat-shaped growth.
