Magpie Maggie was a female anthropomorphic duck.
"Magpie Maggie" was a witch living in early colonial Duckburg. Petty thief Slippery Finn attempted to steal an emerald ring in her possession, dealing her a deadly injury in the process. Maggie used her last breaths to curse the ring to become a prison for Finn, hiding it in her underground lair beneath the Duckburg Cemetary.
Behind the scenes
Magpie Maggie only ever appeared in the 2017 tribute story One For Sorrow.
