The Plab Patty is a burger made by Mr. Krabs and Plankton in the episode "Friend or Foe." It poisoned Old Man Jenkins. However, he was later found alive in the future. It was inspired by the food from Stinky Burgers, a business made by Mr. Stinky.
The Plab Patty knocked Old Man Jenkins out because it was poisonous. One of the secret ingredients is a pinch of chum.
The Plab Patty looks 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. At least one version is known to contain 2 parts seaweed sauce, 1 part squid ink, and 3 parts dried kelp.
- The Plab Patty's name is a combination of Plankton and Mr. Krabs' names, as they were the creators of the burger.
- It is the prototype of the Krabby Patty.
