A second TV series, also called "The Berenstain Bears", debuted on PBS in 2003. The series was produced by the Canadian company Nelvana and consisted of 40 30-minute episodes adapted from the books and also a few new stories as well, similar to the 1985 production. However, the series are considered separate adaptations and were never aired together. Even though the 2003 series is not a remake but a continuation of the episodes, some characters' personalities changed while other characters no longer appeared. (However, new characters appeared.) The original specials and TV series have a rustic design and interaction with other forest animals, while the Nelvana series completely embraced rural life with slower timing. Additionally, as a Canadian production, due to Canadian laws requiring Nelvana to employ only Canadian writers and artists, the Berenstains' involvement in the program was limited; They sought to exert their influence on some details, according to Stan. "Our bears don't wear shoes, and Papa wouldn't wear his hat in the house...And we try to keep complete, total banality out of the stories." Common practicalities of animation did force some minor costume changes from the books, such as eliminating polka dots and plaids. (This issue also occurred in previous animated series and specials. Only a limited amount of polka dots was allowed in the five specials.) The show's theme song is performed by Lee Ann Womack.
