The Animal Pyramid World Championships are under way. There are only two minutes left before the starting whistle is blown for the grand finale. The players try to pile their animals, as skillfully as possible, to form a collective pyramid. But watch out as the animals must not fall off! Who will be the next Animal Tower Stacking World Champion?

In Animal Upon Animal: Small and Yet Great!, the players build an animal pyramid by stacking their animals one by one on top of each other, without any of them falling off. The die indicates how many animals can be stacked, where and who shall stack them. Be the first to stack all of your animals in the pyramid and you win!
