I haven't actually seen this movie myself but I read that there is a line where one of the bears mentions accidently knocking down a tree, which was the home of a couple of chipmunks.

Chipmunks are ground squirrels and don't live in trees, they live in holes in the ground.

I saws this film. It was ok in a hippie kinda way.
Guy kills bear. Guy gets turned into bear. Guy meets bears cup. Guy adopts cub. Killing bears bad.
