The Berenstain Bears - 3x28 - Big Bear, Small Bear- Followmy.tv

When she adopts a baby chipmunk, Sister learns the hard way about trying to keep a non-domesticated animal as a house pet. As a baby, all the chipmunk does is eat and sleep. However, the bigger it grows the more active it gets, and the more mess it makes the more trouble it causes. Of course, none of it's intentional. That's just the creature's nature. But when it accidentally bites Papa, Sister finally realizes that if she really loves little Brown Eyes, she'll do what's best for the chipmunk and return him to the outdoors where he belongs.
