Shirley's Aura ranaway from Shirey and a joined gang of vicious criminals and cutthroats.
- Shirely's Aura ironically resembles The Female Pigeon (Hatta Mari) from the 1944 Daffy Duck cartoon, Plane Daffy, with the exceptions of her bow being pink instead of black, her gloves being black instead of dark red, and her speaking in a New York accent instead of a German accent.
- Shirley's Aura appears briefly again in the episode Best O' Plucky Duck Day segment, Sticky Feathers Duck, when she refuse to help Plucky steal a candy bar. This time instead of looking like the one in The Return of Pluck Twacy. she looks like a purple version of Shirley.
- Shirley's Aura made her first appearance in the episode Test Stress episode segment, To Bleep or Not to Bleep.
