Penny is a kind, beautiful, lovable and intelligent teenager. Ever since she was little she loved Bolt dearly and was heartbroken when she found out he ran away. She clearly isn't fond of her agent who rarely listens to her and tries to persuade her into doing what he wants. She is also very loving towards all animals, including Mittens and Rhino, who she presumably found at the hospital and adopted.
Role in the film
Penny was 8 years old when she originally found Bolt in the Silverlake Animal Rescue, who lived with the puppies of the shelter and his favorite toy Mr. Carrot. Five years later, she and Bolt became the stars of the hit television show Bolt. However, Bolt believed everything that he saw to be real, and that he had superpowers. Bolt was assigned the task of protecting Penny from Calico’s henchmen. In one of the episodes, she and Bolt are in a large city, where they are spying on Calico. After "interrogating" one of his thugs and learning of his location in Bolivia, Penny was pursued on her fold-up scooter by Calico’s helicopters and motor cycles. One of the men tried to lead Bolt away by deploying a disc-shaped bomb on the back of a gas tanker. But Bolt swiftly dispatched the bomb and reunited with his mistress. Then, Bolt used his super bark on the forces that surrounded the airport.
After the episode, Penny pleads to her agent to take Bolt home for the weekend, but the agent simply states to “Put a pin in it.” When Penny is kidnapped on the show, Bolt escapes and Penny tries to get him back by sending out lost dog flyers. However, Mindy Parker from the network reminds her that they have to keep in production.
Bolt reaches the studio, finding Penny embracing his lookalike. Unaware that Penny still misses him and that her affection for the lookalike was only a part of a rehearsal for the show, he leaves, brokenhearted. Mittens, on a gantry in the studio, sees what Bolt does not - Penny telling her mother how much she misses Bolt. Realizing that Penny truly does love Bolt, Mittens follows Bolt and explains. At the same time, the Bolt-lookalike panics during filming and accidentally knocks over torches, setting the sound stage on fire and trapping Penny. Bolt arrives and reunites with Penny inside the burning studio, being rescued as they succumb to smoke asphyxiation.
Penny and her mother subsequently quit the show when their agent attempts to exploit the incident for publicity purposes. Penny herself adopts Mittens and Rhino, and moves to a rural home to enjoy a simpler, happy lifestyle with Bolt and her new pets. However it's unknown if she's still an actress after she quits the show.
- Penny is never referred to by her name outside of the show (other than the animals). Her mother calls her by her endearments, and her agent calls her "My Little Superstar."
- Her last name is hinted to be Forrester.
