Supersized Patty Plankton grabs a crumb of a leftover Krabby Patty and zaps it with his Enlargatron Ray. The co-ordinates of the ray are however inaccurate and that causes the Krabby Patty to overgrow and mutate into a living patty, who then takes notice of Plankton. Plankton however decides to fight back with size but the inaccurate ray only makes him the height of an average citizen, not enough to dwarf the patty. Plankton makes a run for it, carrying only his freeze ray. He is pursued by the patty through Bikini Bottom, the Industrial Park, the Jellyfish Power Plant, the Oyster Stadium, and finally through Downtown back to the Chum Bucket. Along the way, he finds a window of opportunity to collect inventory while the patty is sleeping. At the end, Plankton hides behind a coral formation and the patty passes by. However, he gloated about his victory and the patty notices his Antennaes. The patty makes a leap and crushes Plankton.
