Sister Bear

Sister Bear is Papa Bear and Mama Bear's six-year-old daughter who is in the first grade. Her hobbies include playing with dolls and her best friend Lizzy Bruin. She also is quite athletic, which showed in various books that she plays baseball with her brother and runs the "Bear Country 3-mile run" with her family. She can be greedy about her toys, though this generally results in her learning a lesson at the end of the book. Her birth was chronicled in 1974's The Berenstain Bears' New Baby; when she first met Brother Bear as a baby, she punched him instead of greeting him, but they quickly became loyal towards each other. She's best friends with Lizzy Bruin and, to a lesser extent, Queenie and Babs Bruno. She's more social and outgoing than Brother Bear. She was also jealous of the arrival of the new baby Honey Bear and was mad at her family because she felt that her baby sister has replaced her position in the family. She is voiced by Christina Lange in 1985 and Tajja Isen in 2003.
