Tommy Tott, an adventurous young boy, lives in a house with a stream behind it. One morning, Tommy sits beside the stream and wonders where it goes. If he were only very small, he could ride a raft down the stream to its end and see where it would take him. As Tommy sits daydreaming, he suddenly finds his wish granted. He finds he has become a very small boy riding a raft and headed on an incredible adventure downstream! As he floats along, Tommy meets wildlife of all kinds-and they can talk! Not all of the insects and animals Tommy meets on his journey are friendly, however; some even want to eat him! Can Tommy Tott stay safe on this exciting adventure? Will he ever get big again and find his way home?
