Mrs Goose is a female anthropomorphic goose.
Mrs Goose attended a "concerned adults' meeting" about Halloween in Duckburg in 1961, alongside Luke Goose and his father. According to one account, she is Luke's sister, and, more oddly, Gus Goose's mother; many other accounts of Duck genealogy identify Gus Goose's father as being Luke, with his mother being Luke's wife Fanny, who bears a certain resemblance to our Mrs Goose.
Behind the scenes
Mrs Goose first appeared in the 1961 Carl Barks story Jet Witch, and was identified as a relative of the Goose family in Mark Worden's Duck Family Tree (1981). Her design seems to have inspired Don Rosa's own take on Gus Goose's mother Fanny Coot.
