The Plabs Burger is a burger that was made by Mr. Krabs and Plankton in the episode "Friend or Foe." It killed Old Man Jenkins. However, he was later found alived 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's (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 a Krabby Patty. It has the bun, the greens and everything else. The ingredients are seaweed, squid ink, a pinch of chum, and others.
- The Plabs Burger's name is a combination of "Krabs" and "Plankton", the creators of the burger.
- It was the prototype for the Krabby Patty.
