Billy Goat (1973)

Children's game for Ages 4 - 10. Players take turns stacking blocks at the end of the playing surface. Eventually the weight of the blocks will cause the rubber-band loaded billy goat to launch into the wall of blocks, knocking them down. The player who was putting a brick on the wall when the billy goat was triggered is now out of the game. The goat is reset, and play starts over. The last player remaining wins.
