- For the character from return to Monkey Island, see Boybrush Threepwood
Guybrush Jr. was Elaine Marleys pet bloodhound on Booty Island.
He was named after the pirate Guybrush Threepwood because he had a knack for finding her possessions, was otherwise fairly useless and had a habit of getting in the way.
Threepwood took advantage of this skill when he had the dog sniff out a piece of the Map to Big Whoop.
