The manager-employee hat has almost no difference from the regular employee hat, except it is slightly taller, and has the word "Manager" written on it in black, instead of having the blue anchor on it.
The Krusty Krab employee hat is seen in many SpongeBob SquarePants episodes that primarily take place at the Krusty Krab, as well as the films.
In the credits of The SpongeBob SquarePants Movie, a similar looking hat is worn by SpongeBob after becoming the manager of the Krusty Krab 2. This hat is larger than the standard employee hat, and in place of the anchor is the word "manager" in capital letters, going vertically.
The video game of the movie's version of the hat is red with yellow letters, but it is otherwise identical to the one in the movie.
In several episodes, the hat has a slightly different appearance, such as having a white brim instead of a blue one.
The Krusty Krab hat has a tendency to disappear and reappear on characters' heads over a few scene shots.
