Paddy is a yellow duck, with an English accent, who serves as the golf caddy of Marcel, the golfing goose. Paddy is somewhat of a sycophant as he constantly praises Marcel on his golfing skills and refers to him as "Sir." Paddy is evidently more intelligent than Marcel, who sometimes tries to pass off Paddy's words or ideas as his own. Paddy only reinforces this impression by constantly correcting Marcel by referring to him as a French/Canadian Goose whilst Marcel prefers straight French.
Paddy is a helpful duck to Humphrey and Kate, and has a good sense of humor.
Humphrey and Kate ask Paddy to follow the pups and make sure they are okay. Shortly after, Marcel is the one following them, and when noticed by the pups, he says that he is "looking for a field mice".
