The Frogfish is the minor antagonist from The SpongeBob SquarePants Movie. She is a huge red fish creature who lured SpongeBob and Patrick in with an Ice Cream stand, much like how Frogfish use lures on their tongue to lure in unsuspecting prey. SpongeBob ordered Ice Cream and he discovered it stuck to him, and in fright he bit the substance attached to his arm, and ran for it, the Frogfish then revealed herself and chased the Patty Wagon, almost to combustion. SpongeBob and Patrick jump out of the Patty Wagon for the Frogfish to devour, but she was swallowed whole by a Giant Eel from the monstrous trench.
- Stephen Hillenburg was fascinated by the habits of the Frogfish, so he decided to add this one to the film.
- During the Snap Happy level in the video game adaptation of SpongeBob's Atlantis SquarePantis, a Frogfish can be seen hanging from the ceiling, and SpongeBob quotes: "There's big, and then there's really big."
