Episode 4055

While staying at Gina's, Baby Bear gets a call from Papa Bear at the hospital saying that the baby has been born and he's now the big brother to a baby sister. Gina then drives Baby Bear to the hospital where he reunites with his parents, who introduce him to his baby sister: an adorable little bear cub with soft light brown fur, and a tiny pink bow in her curly hair; Baby Bear is amazed at the fact that all she can do at the moment is pretty much sleep a lot, but as he holds her for the first time, she wakes up and meets her new big brother. Gordon, Gina, and Maria also drop in to see the baby, and after a comment that she looks a lot like her new brother, Baby Bear begins to list off the differences between them, including her curly hair (which he then casually mentions that she's a "little curly bear"), which catches Mama and Papa Bear's ears and declare that Baby Bear just gave her her name: Curly Bear. Later that afternoon, the Bear family makes a pit-stop on Sesame Street to introduce Curly Bear to everyone as well as Baby Bear showing her the highlights of the street.
