He is a muscular, lavender fish with blonde hair and a small mustache and wears black sunglasses. He is always seen in his uniform which is blue, with a matching hat. His police suit consists of a black belt, black boots, and a baton.
Al Priss always seems to be in good spirits. Although cheerful to his wife, he can be shown to be ignorant as he didn't recognize Miss Gristlepuss' hatred to Krabby Patties. In segments of the episode, he is shown to be hungry occasionally.
He is summoned by his wife to close down the Krusty Krab as she opposes "fun and delicious" foods. Mr. Krabs persistently opens a secret Krusty Krab, but he isn't entirely secure from the law. Miss Gristlepuss uncovers it with Plankton's help and brings the SWAT Team to purge it off the Krabby Patties and arrest Mr. Krabs.
However, due to the Chief's liking of Krabby Patties, Miss Gristlepuss is angered, but when she trips over a Krabby Patty and it drops into her mouth, she has a change in heart.
