Earth Day is fast approaching, and that means it's time for another cheerful documentary from DisneyNature. Tim Allen narrates this tale of a 3-year-old chimpanzee separated from his troop in Tanzania and adopted by a full-grown male.

The result is a throwback aimed squarely at the littlest of tykes. 78 minutes G.
