The Giant Clam is an animal that tried to eat Sandy. SpongeBob rescued Sandy, but SpongeBob then got stuck in the clam's mouth. Sandy tosses the Giant Clam in the air and it fell to its demise. However, SpongeBob was freed. This happens in the episode Tea at the Treedome. In No Free Rides, SpongeBob sees a sign called "Giant Clams" and huge clams start eating SpongeBob while he is holding onto his boat, being driven by Mrs. Puff. Old Blue Lips, a giant clam appears as the main antagonist in CLAMS. In Porous Pockets, a giant clam choked on a pearl, in which SpongeBob and Patrick took, used for Volleyball, and sold, which triggered SpongeBob to be very rich, thus angering Patrick. Giant Clams in real life are the largest Mollusks, so it's understandable that there was a struggle for SpongeBob and Sandy.
Giant Clams appear as enemies, and helpful obstacles in Nicktoons Unite!. They have to be used as bouncy platform to continue in levels. When you come close to it, it will bite you. Even when you stand on the clam it will try to bite you, but because of that you will be launched upwards and can continue.
