Stinky Burgers was the only place to buy a burger in the time when Mr. Krabs and Plankton were kids. It was a fast food business owned by Stinky, a rich man who was quite overweight. It's only appearance so far is in the episode "Friend or Foe"
Stinky Burgers was a small store, with an average look. It had a metal roof of a low quality and the sign was orange with a bold yellow "Stinky," and a black Burgers text. Next to that was a dried out clam that was spouting out a smelly, fake breath. It had a small foghorn coming out from the left side, an ordering window and a door that only Stinky was able to enter. Inside Stinky Burgers was a kitchen, although nothing was shown inside. You did not eat inside though. Outside the cooking area were seats and chairs with an umbrella, shielding bad sun or rain. They were not of great quality. Their was also an overfilled trash can on the right. The whole area was surrounded by a very low brick wall. The fact that Stinky did not put more work and care into his business is surprising because of his success, fortune, and "love for the kids".
Food and Inspiration
The food was not perfect, but it was the only place to get a Burger. This gave Plankton and Mr. Krabs an idea to make their own burger called the Plabs Burger. It has been theorized that the Plabs Burger was the inspiration for the Krabby Patty.
Because Stinky Burgers was quite filthy, it was closed down for cleanliness issues. Outside the brick wall was also a bin that was spilled, that caused bad germs, therefore making Stinky Burgers contaminated and disgusting.
