The Ghost of Plankton

After watching a horror movie, Plankton is inspired to become a ghost and get the secret formula. However, he is unable to physically grab the bottle. The Flying Dutchman offers to teach him how to be a ghost, with topics such as haunting houses and making scary faces. When Plankton is finally able to pick up the formula, he realizes that he cannot take it out of the safe; he returns to the Chum Bucket to find that a funeral is being held for him, and tries to get his ghost back into his body.
