The donut is shown when Lord Poltergeist puts Mr. Krabs, Patrick, and Squidward into a void. The donut attempts to annoy, torment, and aggravate Patrick by sticking to his head. Every time Patrick tries to reach the donut, it makes his head extend, making it impossible for Patrick to reach the donut. The donut soon notices Patrick's sudden lack of interest in it and takes on many forms of foods, though it becomes annoyed and tells Patrick to pick one to continue his eternal torment.
However, after Patrick wants it to return to the donut form, it screams at horror at the thought of having to deal with his stupidity for eternity, ironically allowing Patrick to outsmart his torment.
Later in the episode, the donut is shown working at the Krusty Krab, only to have a fish bite off a part of him, but the remainder charges him for eating.
