Pepper is a seasoning that first appears in the episode "Goo Goo Gas."
It is a gray and black seasoning. In "Unreal Estate," it comes in a silver can with a blackish-gray label that depicts an illustration of the pepper within a white square centered in an orange border. Above this, the product's name is transcribed in yellowish-orange letters. The top of the can has omission holes for one to season their food with when it is turned upside down.
Squidward uses pepper as one of the ingredients in a meal he is cooking. As hammering on nails is heard, the pepper shaker flies into the air and spills into one of his plants. As the flower plot tilts, the pepper is spilled onto Squidward's rug.
After being sprayed with a hose by him, Squidward has had it with SpongeBob's antics and is desperate for him to move away. As a result, he convinces him that he is allergic to his own house, by breaking into SpongeBob's room while he is sleeping and proceeding to clog his alarm clock with pepper.
The following morning, SpongeBob wakes up to his alarm clock omitting the smell of pepper and starts to agree with Squidward that he is indeed allergic to his own house, wanting to find a new one afterwards.
While the miniversions of SpongeBob and Patrick are torturing their respective creators, mini Patrick pours an entire shaker of pepper into Patrick's nose in an attempt to make him sneeze.
