Role in series
When SpongeBob, Patrick, and Squidward are stuck in the Kelp Forest, SpongeBob brings out the Magic Conch Shell and he and Patrick play with it, ask it questions then pull the cord, and do whatever it says. It serves as the head of their club. SpongeBob and Patrick are loyal to the conch shell but not Squidward, who calls it a stupid toy. It tells them to do nothing, which SpongeBob and Patrick obey while Squidward unsuccessfully tries to leave. When the foods arrive, Squidward asks it numerous times for food but the Conch constantly answers "no" every time, infuriating him.
When a Forest Ranger arrives to assist SpongeBob, Patrick, and Squidward, he reveals that he has a conch shell of his own, much to Squidward's shock and SpongeBob and Patrick's delight. It once again tells them to do nothing, and this time the still shocked Squidward obeys.
It, along with several other objects, can be seen on the floor of SpongeBob's house when SpongeBob is bored.
The Magic Conch club is a club that appears in the episode "Club SpongeBob."
