Nana Cadabra Fairywinkle is the mother of Big Daddy, the grandmother of Wanda and Blonda, and the great-grandmother of Poof.
Things That One Knows About Her
Little is known about her because she has only appeared in a Turbo Nick short called "Fairly Family Tree". She is likely Italian, as her sons speak very fluent Italian and would refer to Wanda as "Little Cannoli".
Trivia
She may be a parody of Carmella Corleone, from the Godfather trilogy.
