A cute story of cooperation, it’s got a lot of repetition in the text, which gives it the flavor of a folk tale that might have been handed down by word of mouth, and makes it good for beginning readers.  It tells of a group of animals who are trying to reach the moon to take a taste:  One animal after another finds it just out of reach, and calls upon another animal to climb on it’s back, until there is a whole tower of animals.  The moon, thinking it is a game, keeps moving out of reach, until it grows bored with the game and decides the small mouse at the top of the tower can’t do too much damage, so he lets the mouse take a taste, which he shares with the others.  A fish who watches the whole thing can’t imagine why the others are all working so hard to reach the moon in the sky, when there’s another so much handier in the water.
