You're the chief of Rapid River Village!
You control the secret cave, the watchtower, and tree trunks that fall at your command. Push one gray brick to the right and a trapdoor drops intruders into the secret cave! Push another gray brick back and drop logs through a second trap door. Includes two tepees, a canoe, campfires, totem pole, two horses, seven figures, and two hollow tree trunks to hide in.
