Sister Bear (🇯🇵Japanese:シスター・ベアー[Shisutā Beā] ) is one of the main characters of the Berenstain Bears series. She is Papa Bear and Mama Bear's second child and Brother Bear's younger sister (by two years); and as of The Berenstain Bears and Baby Makes Five, she is a middle child. Sister Bear is 8 years old and in the third grade.
Sister was first introduced in The Berenstain Bears’ New Baby in 1974.
Sister Bear is a highly-competitive, born-to-win, self-reliant third-grader, who is often braver than she imagines. She loves acting, her Bearbie dolls and the color pink. Sister is very outdoorsy and sports-minded, but she also loves fairy-tales, writing, the color pink, playing with dolls and jump rope.
Sister's usual outfit consists of a white long-sleeved blouse with pink polka dots, frilly pink overalls, white camisole, matching panties and a pink ribbon tied in a bow. The color pink is always used on her outfits, even when she is dressed in costume (e.g. her costume in The Berenstain Bears Get Stage Fright and her costume in The Berenstain Bears Trick or Treat). In the animated series, the polka dots on her blouse are omitted, most likely because it helped simplify the animation process.
