A lesson in envy/jealousy The Penguins visit a small planet divided by a picket fence round the equator and populated by two factions of sheep, each of whom want to conquer the other side. Michelle also has her eyes on Jason's room, which she believes to be bigger than hers. The pervasiveness of Envy causes green-eyed Monsters to appear and eat holes in everything they see. It's only when contentment rules that peace is restored.
