Role in the series
Gustav Goose made his first appearance in the series in the episode Ducks by Nature.
Gustav Goose reappears in the episode Ducky Dearest when Huey, Dewey, and Louie are talking with him on the telephone. He plays in the bell for Donald Duck opening the door for him, when Gustav Goose opens the door Donald begins to curse him. Gustav Goose is shown for the last time when he is sleeping at home.
- Gustav is not the same character as Cousin Gus, due to there being very few similarities (aside from the name and general size of the character). Some confusion is also caused by the German comicbook version of Gladstone Gander being referred to as "Gustav Gans" ("Gustav Goose").
