Penny is said to be athletic and goofy in personality. She is featured in Minnie ‘n Me; a merchandising line of products. They were collector’s cards and books designed for pre-teen girls. She forms a trio with Minnie and Daisy, much like the trio of Mickey, Donald and Goofy.
There is fan speculation that she could possibly be the (future) Mrs. Goof and mother of Max Goof. This is based off the fact that she has red hair and a reddish nose like the description of the mysterious Mrs. Goof.
