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/Mrs. Geef 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/Geef.
