The Health Inspector is an unnamed character that only appears in the episode "Greasy Buffoons."
This Heath Inspector is much different from any other health inspectors. He wears a suit and drives a large boat. He appears after SpongeBob makes the call informing him about the grease. Mr. Krabs and Plankton tried hard to keep him quiet but SpongeBob eventually told the Heath Inspector that they were feeding people grease. The Heath Inspector hears this and thought he recognized the smell of the grease, but he also thought the smell might have been because either Mr. Krabs or Plankton just hadn't 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 on his boat.
