This is a storybook adventure that gets kids up and moving, while playing with their favorite Sesame Street characters and new monsters they meet along the way. They help Cookie Monster and Elmo in their quest to assist Marco with her birthday party planning. Along the way, they perform tasks -- but not just mini-games; they\'re actually interacting with the characters in the game, like tossing a ball of trash into a garbage can on screen, running along with them or flying by flapping their \"wings.\"Mixed in are lessons about cooperation and sympathy, and grownups hope that as in the TV show, they will learn to cultivate friendships and conquer their fears, right from their living room.The game is designed so that two players can play at once, so a parent or sibling can join in. They can drop in or out of the game at any point, which is nice since a little one\'s patience for getting to the end of a game is sometimes lacking.The games are just as much fun with one player because kids are using their whole body as the game controller, so they\'re fully engaged with what they\'re doing.
