Wildman

An adolescent boy draws the shortest lot in a grim dystopian children's game in which he must hunt down a mythical man-beast, WILDMAN, and bring back a lock of its hair before the other children find him. Under chase by the other children, the boy abandons the path for the deep woods. As he journeys, the forest comes alive around him culminating in the figure of the Wildman, an injured and vulnerable creature made of leaves and sticks. - IMDb
