Role in episode
Prior to the beginning of the episode, the genie lent his genie bottle to Plankton while he is away on vacation. He appears in person at the end of the episode after he hears about Plankton's intention of breaking the bottle as part of his plan to get the Krabby Patty secret formula. He is angry at Plankton that his bottle gets damaged while under his care, but Plankton cared less and Mr. Krabs is shocked to see an actual genie.
Squidward and Patrick arrive at the scene and they both try to claim the bottle as theirs. The genie is outraged at their greed and sees that they have desecrated the great spirit of the bottle. As punishment, he shrinks the scared Squidward, Patrick, Mr. Krabs, and Plankton and traps them in a different bottle with his magical powers. The genie disappears with his bottle as he promised that he will take it with him when he visits his mother.
The genie has a few similarities to Genie from the 1992 film, Aladdin.
