Krabs sometimes identifies himself as a sailor, most likely because he did serve in the Navy at one point. The Navy was where he earned the nickname "Armor Abs Krabs". During his service, he was the chief janitor on the S.S. Gourmet and "head chef" on the "S.S. Diarrhea". Sometimes when he appears onscreen, sailor's music is played; Krabs uses sea-faring vocabulary; he calls his staff his 'crew', and the disagreement as 'mutiny', calls the bathroom the head while his laugh is also appropriate ('Ar 'ar 'ar 'ar 'ar'). In contrast to his namesake, Krabs is something of a miser; he is known to go insane if he has to give up so much as a penny. In "Born Again Krabs", he gave SpongeBob up to the Flying Dutchman for sixty-two cents, but repented later. When customers leave the restaurant because they do not like the food (which is usually due to SpongeBob or Squidward's inaccuracies), he uses catchphrases - these include "That's me money walkin' out the door!", or "There's gonna be a few changes around here!"
However, he's a caring and thoughtful crab; he appreciates his employees, SpongeBob SquarePants and Squidward Tentacles (who help keep his restaurant afloat), dotes on his daughter, Pearl Krabs, and in one episode, he found his second love (after money), Mrs. Puff (in "Krusty Love" wink . Mr. Krabs' arch-rival and somewhat friend is Sheldon J. Plankton, the owner of rival restaurant The Chum Bucket across the street from his establishment. He has a mother, Mama Krabs, who lives in a near identical version of his anchor home, except it is pink. His address was also revealed to be 3541 Anchor Way. Krabs served in the Navy, where he earned the nickname "Armor Abs Krabs." Mr. Krabs tries to keep it cheap when purchasing anything, even though he's the richest crab in the ocean, which often results in Pearl becoming extremely disappointed in her gifts, such as on her 16th birthday or the infamous Squeaky Boots. Mr. Krabs also owns a pet worm named "Mr. Doodles" as seen in the episode "As Seen On TV". It is also shown in the episode Mid-Life Crustacean that he can extend his arms to great distances to collect items.
