The Sponge Patty resembles a Krabby Patty except it has two light pink sponges used for the bread buns. Other ingredients for this inedible food include an aluminium brush for the patty, lime green soap as the special sauce, and mop strings as the lettuce.
Role in episode
SpongeBob accidentally creates the Sponge Patty after Plankton, who is inside of him at the time, removes his eyes. Plankton's plan is to see how SpongeBob makes a Krabby Patty right with his own eyes, but doesn't realize that SpongeBob can't make a Krabby Patty blind. After SpongeBob constructs the Sponge Patty and hands it to a customer, Plankton replugs his eyes and SpongeBob is horrified to see the Sponge Patty he made.
