He is the employee of Mr. Plankton in the alternate universe. He gives his boss two Krabby Patties for bun inspection, which he takes to his office. Just as Plankton gets intimate with the burgers, SpongeBob comes into his office asking for criticism on his fry cooking skills. Plankton tells him that he is using too much sauce, which destroys SpongeBob's confidence and leads him to cry until Plankton offers him a promotion.
Later, SpongeBob panics as Mr. Krabs comes to steal the Krabby Patty secret formula, so SpongeBob serenades him with a clothes canyon until he gets a bra on Krabs, prompting him to give the patty back.
Alternate-Universe SpongeBob is seen through Mr. Krabs' mirror when SpongeBob tries to figure out how to prevent Mr. Krabs from seeing the paint he and Patrick got on his first dollar, but he leaves when Mr. Krabs comes home, then telling SpongeBob that he is on his own.
He gets eaten by a monster as part of a long string of jokes told by the Flying Dutchman to scare SpongeBob.
SpongeBob SquarePants (clone)
SpongeBob and Alternate-Universe SpongeBob are a lot alike. However, his alternate-universe counterpart acts more dramatic than usual in "The Algae's Always Greener." Contrary to the main-universe SpongeBob, Alternate-Universe SpongeBob appears to have a bit of a rude streak; in "Wet Painters," he refuses to help SpongeBob, and in "Something Smells", he breaks the mirror he is in upon smelling SpongeBob's rancid breath, alluding to suicide.
