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 two 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.
The old version of the hat from SpongeBoy Ahoy! had a "C" on it instead of an anchor.
Each of the seven main characters has worn a Krusty Krab hat at least once in the series.
SpongeBob - Most episodes featuring the Krusty Krab
In some episodes, SpongeBob takes off his Krusty Krab employee hat at work and leaves it there when he is done his last shift of the day. In other episodes, SpongeBob takes off his Krusty Krab employee hat when he comes home from work. Likewise, in some episodes, SpongeBob puts on his Krusty Krab employee hat when he is leaving his house. In other episodes, SpongeBob doesn't put on his Krusty Krab employee hat until he arrives at work.
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.
Most of the time, the Krusty Krab hats stay on top of employees' heads even when they should not logically be able to. However, forces such as the wind and water are sometimes capable of pushing the hat off.
