Grubstake Goofy was an anthropomorphic dog.
Description[]
The son of explorer Goofmors Goofy, Grubstake Goofy, brother of Ebenezer and Windjammer Goofy, set up a dishonest business in the Misery Mountains, selling false maps to the Lost Mule Mine along (with expensive mining equipment) to chumps. He died at some point before 1957. In 1957, his grandnephew Goofy found one of Grubstake's false maps inside the portrait frame he'd inherited of him, and thought it genuine.
Behind the scenes[]
Grubstake Goofy was only ever featured in the 1957 story The Lost Mine of Misery Mountains.
