The many hats of Louie the rat

Summary: "Louie the rat likes making useful things out of not-so-useful things. But none of the other rats seem to appreciate his crazy inventions, which often turn out to be not so useful after all. So when Louie notices his fellow rats wearing fancy, colorful hats -- huge hats that don't fit through doorways, heavy hats that are difficult to walk in, ridiculous hats that make it impossible to see -- Louie decides to make hats that are USEFUL. He makes wool hats for warmth, wide-brimmed hats for shade, and hard hats for safety -- and of course he makes them all out of his never-ending supply of not-so-useful things. At first, Louie is sad when the other rats don't seem to care about his useful hats. But a few simple acts of kindness lead to a growth in his hat business and, eventually, he's able to save the day with his most useful hat of all."--Provided by publisher.
