List of characters

Doctor Krabs (A.K.A. Dr. Eugene H. Krabs) is an alter-ego of Mr. Krabs seen in a mid-1980s Krusty Krab commercial. He states that eating Krabby Patties improve your health, though, this is not the case. His only appearance is in "Truth or Square." 


  • He is just pretending to be a doctor so that fish could, and would eat Krabby Patties.
  • He was only seen once in a commercial.
  • He was portraying as a doctor, which, in fact, is illegal, but has been done by Patrick twice, in the episodes "Suds" and "The Splinter."
