Sonny Munroe is the newest castmember of the kids sketch comedy series So Random! She is played by Demi Lovato, and is known by her cast and crew as the nice girl from Wisconsin. Friendly and caring towards those around her, she does her best to help other people with their problems and attempts to achieve her dreams, but earns mixed results.Sonny has a crush on teen heart-throb actor Chad Dylan Cooper, who is the star of the teen prime-time soap opera MacKenzie Falls, which shares a studio on the same lot as So Random. However due to a rivalry between the casts of both shows, and Cooper's own arrogance, and obliviousness to life outside of Hollywood, she tends to conceal her feelings from others.
