Captain Crook was the McDonald’s advertising character associated with the Filet-O-Fish sandwich.
Captain Crook appeared as a pirate-themed figure in the McDonaldland advertising world. His sailor and pirate clothing connected him visually with seafood, while his role helped McDonald’s give the Filet-O-Fish a character-based identity distinct from its hamburger products.
The character was part of the broader group of McDonaldland figures used in television commercials and promotional materials. These mascots created recurring stories and made menu items easier to distinguish for young audiences.
Captain Crook is sometimes confused with the Hamburglar because both characters were portrayed as mischievous food-seeking figures. Their associations were different, however: the Hamburglar focused on hamburgers, while Captain Crook was linked to the Filet-O-Fish. Mayor McCheese and Officer Big Mac were also separate characters with different roles.
