Role in episode
The bottle is first seen rolling over to Karen in the Chum Bucket while she is cleaning the laboratory. She does not recognize the bottle. As she opens it and looks, Plankton appears out of the bottle with pink sparkling dust. Karen does not recognize him, as he is wearing a genie costume. She scans him and finds out it is actually her husband, Plankton.
Plankton uses the bottle to make Mr. Krabs believe that it is a genie bottle as Plankton puts the bottle right in front of Mr. Krabs' house. Krabs instead kicks the bottle straight to the Krusty Krab while reading a newspaper. When the bottle lands at the Krusty Krab, Mr. Krabs asks SpongeBob to put it in the trash. As soon as SpongeBob is about to put it in the trash can, SpongeBob looks at it and is fascinated by it.
He later tells Mr. Krabs that he is going for his lunch break. SpongeBob then walks to his house while playing with the bottle, which tortures Plankton. He then shows Gary. As SpongeBob finds out the bottle is magic, he rubs the side of the bottle for a genie to come out. Eventually, Plankton comes out of it and attempts to trick SpongeBob to take him to the Krusty Krab, while SpongeBob does not realize it is actually Plankton.
SpongeBob asks Plankton to make a wish for three of his friends, including Squidward, Patrick, and Mr. Krabs all in order. Plankton grants all three of those wishes and all three are astonished by the bottle. All three of Patrick, Squidward, and Mr. Krabs try to fight over the bottle, as they believe it is real and all try to possess it so they can get three more wishes.
SpongeBob comes up with the idea of spinning the bottle and whoever it lands on, it is theirs. It at first lands on Squidward, but Plankton inside rolls it to the left side to Mr. Krabs. As Plankton gets dizzy, he cannot take it anymore, as he admits the genie was him all along and cannot keep up the charade anymore.
The real genie appears and is angry at Plankton that his bottle got damaged while under his care, but Plankton and Mr. Krabs care less.
Squidward and Patrick arrive at the scene and they both try to claim the bottle is theirs. The genie is outraged at their greed and sees that they have desecrated the great spirit of the bottle. As punishment, he shrinks Squidward, Patrick, Mr. Krabs, and Plankton and traps them in another bottle with his magical powers.
The genie then disappears with his bottle, as he promised that he will take it with him when he visits his mother.
