The game doesn't need this premise to exist as the design works well on its own, but the concept gives you a package, a framework in which to think about the game. And as eggertspiele did with Camel Up and its unnecessarily awesome pyramid, the publisher has used simple cardboard to provide players with well-designed bits, specifically four cardboard arks that players use to hold their animal tiles during the game. When you first open the box, you see a few punchboards floating in air and think, "That's it?!" Then you punch out and assemble everything, and suddenly you barely have room in the box to fit it all!
