Role in episode
He appears after SpongeBob makes the call informing him about the grease. Mr. Krabs and Plankton try very hard to keep him quiet to protect their profits but SpongeBob eventually tells the health inspector that they were feeding people grease. The health inspector hears this and thought he recognized the smell of the grease, but he also thought that the smell might have been since either Mr. Krabs or Plankton just had not bathed in a while.
He then orders both the Krusty Krab and the Chum Bucket to be shut down until the grease is cleaned up. He then drives away in his boat.
