Young and innocent fairy Crysta (voice of Samatha Mathis), who calls the rainforest of Ferngully her home, rescues human Zak (voice of Jonathan Ward) from an out-of-control logging machine - by shrinking him down to fairy size. Unfortunately, she is unable to return him to his own size, and Zak ends up involved in a fight not only against the loggers who are deforesting Ferngully, but also against the evil Hexxus (voice of Tim Curry), who the loggers accidentally free from the tree where he is imprisoned. FERNGULLY: THE LAST RAINFOREST also features a bevy of celebrity-voiced supporting characters, including Robin Willams as a bat who escaped from an animal testing lab and Christian Slater as a young sprite who is in love with Crysta.
