Animal Upon Animal: Christmas Edition is a special winter-themed edition of Animal Upon Animal. The animals are climbing all over each other to form an ever-taller Christmas pyramid. But which one will make it to the top? The players decide by carefully balancing squirrels, snow bunnies, penguins and reindeer on stars, fir trees, sleds, and even on top of each other. The first player to place all of their figures safely onto the pyramid wins this wobbly Christmas stacking game.
