There once was a happy little possum, the happiest animal in the entire forest, who always wore a great big smile. This jolly creature was content simply to hang by his tail from a tree until he was discovered by a group of picnickers. Mistaking the possum's upside-down smile for a frown, the people resolve to rescue him - and they turn the little possum's world topsy-turvy. Viewers of all ages will appreciate the message of this memorable satire of cultural intolerance.
