Goldie dropped Dickie off because she couldn't take care of her anymore. She was left in the care of Scrooge McDuck.
Sometimes she worked as a reporter for Brigitta McBridge or for Scrooge's little known brother Gideon McDuck.
In Brazil she appeared in her own series with her friends Neptunia, Olivia, Walter, and Beckett in a series of stories titled Os Adolescentes (translated loosely from Portoguese to The Teenagers) as a bonus story in Ze Carioca (a comic book starring José Carioca). The connection between Goldie and Dickie is generally ignored since they only made one appearance together.
