Humble Harry is a ride attendant at the Pupu Goodtimes Amusement Park.
When Albert and Jumbo Shrimp told Oscar that they could win a fork saber if they could knock down the cups, the attendant turned out to be Humble Harry. Humble Harry has a medical condition where he goes paranoid when he sees someone who's unhappy. Jumbo, Albert and Oscar failed to knock down all of the cups, making Humble Harry tell them they aren't leaving until they win. After many failed tries, Humble Harry, seeing the three so unhappy, asked if he can just give them the fork saber. Jumbo denies it, and the three later decides to throw the ball from the Pup-anator rollercoaster to knock the cups. They succeed, and Humble Harry happily throws the fork saber to them. Humble Harry is last seen driving the school bus back to Freshwater ("Good Times at Pupu Goodtimes").
