Penny is Bolt's owner and best friend and the secondary tritagonist of Disney's 2008 animated film Bolt.
Penny is a kind, lovable, and intelligent 13 year old girl. 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, whom she presumably found at the hospital and adopted.
Role in the film
Penny was 8 when she adopted Bolt in the Silverlake Animal Rescue, who lived with the puppies of the shelter and his favourite toy Mr. Carrot. Five years later, she and Bolt became the stars of the hit TV 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 motorcycles. 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 person. Then, Bolt used his super bark on the forces that surrounded the airport. Having accomplished their mission, Penny poses for a Polaroid picture with Bolt before carrying him through the debris of "super barked" cars and "unconscious" evil henchmen into their set trailer. Penny adds the newest picture to her wall of countless pictures of her and Bolt before trying to play with Bolt, who is convinced the henchmen will come back for Penny and is determined to protect her. Sadly, Penny hugs Bolt goodbye for the weekend and leaves him in his trailer.
Saddened about having to leave Bolt alone again, Penny pleads to her agent to take Bolt home for the weekend, but the agent simply tells her to "put a pin in it." When Penny is kidnapped by Calico 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, or else good people will start losing their jobs.
After undergoing a cross country journey back to Hollywood from New York, 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, broken-hearted. 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.
Penny is only referred to as such on the TV show (and by Bolt and the animals), meaning that her real name outside the show is unknown.Her mother calls her by her endearments, and her agent calls her "My Little Superstar."
Chloë Moretz was the first choice to voice Penny and apparently recorded all of the character's lines. However, she was quickly replaced by Miley Cyrus, who re-recorded a majority of Penny's lines. Moretz's voice work as young Penny is still in the film, though.
Penny is named after the character from the Inspector Gadget series.
