Role in episode
Incidental 41 walks into a shortcut that reads "Shortcut to the Chum Bucket," thinking that Plankton made the shortcut, but instead ends up in the Krusty Krab. Mr. Krabs and SpongeBob introduce Nat to their own version of chum, which he dislikes and throws up after giving a try, and so heads back to the Chum Bucket.
- After Nat tastes the chum and throws up, he comments that it is the "second foulest thing [he] had ever tasted," implying that Plankton's chum is the foulest thing he has tasted, which foreshadows the ending of the episode.
- This proves that Mr. Krabs is able to make chum better than Plankton, even though chum is the only thing that Plankton can cook.
