FernGully is a 1992 animated film - the full title being "FernGully: The Last Rainforest." The story is about a rainforest in Austrailia, which is being cut down. One of the lumberjacks, Zak, is magically shrunk by a fairy named Chrysta, and only then does he begin to realise the beauty and connectedness of the forest. So he teams up with the forest folk to fight the evil Hexxus, which is this evil spirit type thing who thrives on pollution and the destruction of nature.

The cast is great. Comic relief is awesome by Robin Williams, as per usual.
