Tower of Bunnies

Also called "Bunny Paletti" or "Villa Rabbitti." Build a tower out of little plastic bunnies and cardboard discs. Roll a special color die, and pull out a bunny of the appropriate color. The winner of the game is the player who has the most bunnies when the tower falls! Notice the year of copyright. Which came first, the bunny or the Spiel des Jahres?
