When Hillenburg first created Mr. Krabs, his and Pearl's surname was spelled with a C rather than a K. Thus, the name of Krabs' restaurant was the "Crusty Crab." Hillenburg changed the name shortly before production began on the show's pilot episode, deciding that K's were funnier and more memorable. The decision to have Mr. Krabs and Pearl live in an anchor was made after production on the first season had started. The original map of the show's setting, which Hillenburg showed Nickelodeon executives as part of his pitch to the network in 1997, did not include an anchor house and instead labeled the Krusty Krab as both of the characters' residence.
