|List of characters|
In the Mr. Plankton Universe, SpongeBob SquarePants is presumably born the same day as his traditional mainstream counterpart was. He was also a presumed high school graduate, and works for Plankton in the non-mainstream Krusty Krab.
He started working for his universe's Plankton flipping Krabby Patties like his mainstream counterpart did for the mainstream Mr. Krabs. He also helped defend the Krusty Krab from Krabs that lives to destroy Mr. Plankton's restaurant. One day, the mainstream Plankton traveled to this SpongeBob's universe. SpongeBob confused that Plankton for his Plankton. After Plankton wanted two Krabby Patties, SpongeBob told him they were for the customer and gave him two other patties. Just a little bit later, SpongeBob asked for his weekly report review. Plankton, inexperienced, told SpongeBob he was using too much sauce, causing his eyes to become slanted, his lips deform, and his arms to spasm, making noises as if he was about to cry. This scene has become famous. So Plankton promoted SpongeBob to co-cashier. After SpongeBob gave a customer the wrong size drink he kept saying that he soiled the Krusty Krab's good name. After Krabs invaded the Krusty Krab, SpongeBob shot clothes at him and successfully got him in an underwire bra. SpongeBob led the victory screech, and since Plankton went back to the main reality, this SpongeBob has not been seen again.
SpongeBob SquarePants is a cute sea sponge, but he is drawn to resemble a kitchen sponge, being rectangular and bright yellow with a dark brown outline. In earlier episodes (i:e Hillenberg-era), he is wider near the top and gets skinnier going further down, but in more recent episodes, he is a more of a regular square shape. SpongeBob has large blue eyes, a long, slightly curved nose, a large mouth with two prominent front buck teeth, and dimples with three freckles on each cheek. He typically wears a white shirt with a red tie, black leather shoes with shoelaces, and brown rectangular pants with a black belt e (the entire outfit is sometimes referred to as his "pants", hence his name). While working at the Krusty Krab, he wears a tall, white hat with a small blue anchor on it as a uniform.
- He seems to respect Plankton as his boss, as he took a light comment heavily, and wishes to impress Mr. Plankton. He does the same thing with Mr. Krabs.
