Gus Goose first appeared in this 1939 short, where he visits his cousin Donald Duck, and proceeds to eat his cousin out of house and home. This prompts Donald to make increasingly more desperate attempts to make his cousin leave.
His original goose honking voice was created by squeezing a bike horn.
In the Disney comics (including those by Disney Legend Carl Barks, who had also worked as a writer on Gus' debut cartoon, Donald's Cousin Gus), Gus Goose is usually seen living on Grandma Duck's farm outside of Duckburg, where he works as her farmhand. Unlike in the cartoons, in which he makes his iconic honking sounds to communicate, he usually speaks in regular words in his comic book appearances.
Gus makes a non-speaking cameo appearance at Fezziwig's Christmas party, dancing with Clara Cluck.
A character who looks like Gus (named Vacation Van Honk) is seen in the episodes "Magica's Shadow War", "Duckworth's Revolt", and "Sweet Duck of Youth". In "Sweet Duck of Youth", he is seen with other friends and relatives of Scrooge McDuck at his birthday party.
Although he never appeared on the show, his name could be seen on a punch card in "Donald's Rocket Ruckus".
Gus reappeared in animation in House of Mouse, where he was featured as a regular character as the club's gluttonous chef. In this series, once again, Gus only speaks in honking vocal sounds rather than saying actual words. Due to his gluttony, Gus has a tendency to eat the food that is meant to be served to the guests himself.
Gus also reappeared in animation in Minnie's Bow-Toons, but unlike his previous animated incarnations, he speaks with a regular voice.
Gus appears with a speaking role in "Duck the Halls: A Mickey Mouse Christmas Special", where he makes a smoothie in a blender and the sound of the blender is mistaken for Donald. He was also seen rejoicing with the other ducks upon hearing that it does not matter where you celebrate Christmas, and that, therefore, ducks (and in his case, geese) can celebrate Christmas, despite the fact that they have to head South during the winter holiday season.
