Being a substitution for Arlene in "Garfield and Friends", Penelope has a similar body shape as Arlene with the exception of her characteristic hair, beauty spot on cheek, blue eyes and smaller lips (light pink in "Perils of Penelope" and "The Genuine Article," darker in the following episodes). Apart from that, Penny has opposite personality to Arlene - she barely cracks jokes at Garfield's expense (at least less frequent than Arlene does) and her relationship looks more like one-sided attraction. In fact, Garfield appreciates Penelope rather for her living in an Italian Restaurant, which can be seen in "The Third Penelope Episode."
