Zimbbos!

It's a game for Ages 3 and up. You throw dice and the number you get is how many elephants you have to add to the pyramid. There are other animals as well.

From the manufacturer: Use your Creativity and Sense of Balance to Build the Most Elephantastic Pyramid! The elephants are ready to impress with this brand new game of balance. Taking turns, roll the die to find out how many elephants you have to add to the pyramid. The player who puts the last elephant on the pyramid wins the game. But watch out! If the pyramid crashes, you lose!
