He is a pale blue fish with a heavy build. He has a shaved beard, faded blue lips, light brown hair, and wears a light tan shirt, a white apron, and a white chef hat.
He looked similar when he was young, but he did not have a shaved beard.
Jim has a rather egocentric persona in that he thinks highly of himself, making himself look vain and then agreeing when SpongeBob says that he is the best. However, he is still pretty friendly and gives some good advice and words of wisdom to SpongeBob at the end of the episode. He tells him that he cannot work at the Krusty Krab or rely on Mr. Krabs' pockets for the rest of his life if he wants to truly be successful and encourages the young fry cook to someday improve his career by leaving. He also warns Squidward that he should not just wait for his clarinet career to take off and he should keep his options open.
He quit working at the Krusty Krab because Mr. Krabs refused to give him a raise and realized that he wanted a legacy of his own.
After his time at the restaurant, Jim went on to work at the finest restaurants in the world. His success allowed him to retire in luxury. Jim has a solid gold mansion, a solid gold lake, and a solid gold limousine. He also has two security guards who work for him.
Role in episode
Jim revisits the Krusty Krab, where SpongeBob, who had heard of him before, meets him for the first time. In the present day, Jim is bald. During his visit, he helps SpongeBob improve his fry cooking. Before leaving, he encourages the young fry cook to someday improve his career and be successful on his own.
At the Krusty Krab, Jim reunites with Squidward and Mr. Krabs, where they reminisce on the good old days. Although, it all ended with Mr. Krabs and Jim, when the former blatantly started laughing at him when he asked for a raise, thinking the latter was kidding, which he was not.
