A little buckaroo is turning two in this birthday book for the very young, the fifth story about the delightful holiday mice. Mischief and near disaster abound when the littlest mouse`s sister and brothers throw him a cowboy-themed party. Through simple rhymes and charming illustrations, readers witness the party preparations, the arrival of the guests, the opening of presents, and the blowing out of the candles, as well as the ensuing fulfillment of the little mouse`s fondest birthday wish: to be a cowboy.
