When she was introduced as an infant in Season 34, Baby Bear had to adjust to no longer being the "baby" of the family. Currently a toddler, Curly is fond of her big brother, whom she calls "Bebo." Unlike Baby Bear, Papa Bear, and Mama Bear, Curly does not like porridge and Curly can growl louder than Baby Bear. Her birthday is May 9.
The episodes containing the story of Curly Bear's birth were collected on home video in Three Bears and a New Baby. In the DVD Elmo's Potty Time, it is revealed that she is in the process of being toilet-trained.
