It looks just like a normal Krabby Patty, only it is much bigger than others. It is also covered in grease, is alive, and eats people.
Role in episode
Mr. Krabs uses Sandy's growth serum on a Krabby Patty and it starts to grow. He and SpongeBob take it back to the Krusty Krab, where it eats SpongeBob's shoe, the cash register, and eventually the entire restaurant. It grows so large that it covers up and eats most of the citizens ofBikini Bottom.
It is later defeated by SpongeBob absorbing it into his body, which makes it "spit out" everything and everyone it had "eaten."
A giant Krabby Patty previously came to life in the video game Creature from the Krusty Krab. However, unlike this version, the Supersized Patty is sentient as a whole, whereas the giant Krabby Patty only contains the meat being sentient.
