The Plabs Burger is a burger that was made by Mr. Krabs and Plankton. It killed Old Man Jenkins. However, he was found alive in the future. It was inspired by the food from Stinky Burgers, a business made by Mr. Stinky.
The Plabs Burger knocked Old Man Jenkins out because it was poisonous (The newspaper says, "Plabs Patty KO (knocks out) Old Man Jenkins"). It is possible that he was also poisoned because the burger was made in a dump, thus making other chemicals attach themselves to the burger. One of the secret ingredients was a pinch of chum.
The Plabs Burger looked pretty much the same as the Krabby Patty. It has the bun, the greens and everything else. The ingredients are squid ink, seaweed, a pinch of chum, and others.
- It was the prototype for the Krabby Patty.
