Which McDonaldland character was a pirate who promoted the Filet-O-Fish?

Captain Crook was the McDonaldland pirate character who promoted McDonald's Filet-O-Fish sandwich.

He appeared among the colorful characters in McDonaldland, the fictional advertising setting created for McDonald's campaigns beginning in the early 1970s. Captain Crook was designed as a pirate with a strong interest in stealing or eating Filet-O-Fish sandwiches, linking the character directly to that menu item.

The character's name is easy to confuse with Hamburglar, another McDonaldland figure. Hamburglar was associated with hamburgers, while Captain Crook's defining product connection was the fish sandwich. McDonaldland advertisements often used these characters in short fantasy stories aimed mainly at children.

McDonald's gradually reduced the use of many McDonaldland characters as its advertising style changed. Ronald McDonald remained the best-known central figure, while characters such as Captain Crook became associated primarily with the brand's earlier television era.
