Squidward vs Mr Krabs
Unlike SpongeBob and Mr. Krabs' father and son-like relationship, Squidward's and Mr. Krabs' is more of a run-of-the-mill employee and employer. It's very interesting and perhaps worth further research that in the season 2 episode "Bossy Boots," Mr. Krabs daughter Pearl refers to Squidward as "Uncle Squidward." This further supports the very long time that Mr. Krabs and Squidward have been acquainted and are not necessarily biological brothers. They do not necessarily consider each other friends but are shown to get along in certain situations. They are shown to have multiple fights with one another, mostly concerning Mr. Krabs' greed or Squidward's lazy tendencies. Although they don't have too much in common, they do have a long history together, as shown in multiple episodes where it is assumed that Squidward was one of the first, if not the first, employees to work for the Krusty Krab. Unlike SpongeBob, Squidward is far more aware of Mr. Krabs' character as a greedy, crustaceous cheapskate who almost exclusively cares about his gain and often shows this attitude toward him directly, though Squidward will sometimes respect and listen to Mr. Krabs' authority. Mr. Krabs does also think very lowly of Squidward, often blaming him for mishaps, though he does still see him as a valued member of the Krusty Crew on occasion.
