|First Appearance||Dumb and Dumber To|
|Portrayed by||Rachel Melvin|
Penny was born to Harry's (and Lloyd's) old flame, Fraida Felcher. Broke, scared and with no clue how to raise a child, Fraida put Penny up for adoption. However she immediately regretted it, but it was too late because she signed away her rights. Penny was adopted by a world renown scientist and grew up happily. As she grew, she displayed an astounding lack of intelligence, and was hopelessly naïve and gullible. When Harry found a 23 year old post card addressed to him from Fraida telling him of her pregnancy, He immediately assumed he was the father, And since he said he was in need of a new kidney, Lloyd suggested they track her down for one. Upon seeing Penny's picture, Lloyd fell in love with her, completely ignorant of the fact he was many, many years older and could have been her father himself.
Penny is a sweet natured, innocent but horribly dumb and gullible girl. She is extremely friendly and trusting, But too much so, as she was willing to accept hugs from complete strangers, as she did when she met Lloyd, unaware of who he was. Because she possessed many of the same stupidity traits that Lloyd and Harry have, It was easy to assume that this young woman was the daughter of at least one of them. However this was not the case as she was in fact the daughter of the late Peter "Pee Stain" Stainer.
