When Mr. King discovers a flower nibbled by a caterpillar, he is NOT happy. So he builds himself a Caterpillar-Catcher and off he goes. But he doesn't notice that his machine is belching smoke, or that he is leaving crushed flowers in his wake. Now his friends are NOT happy and Mr. King isn't very proud of himself. But --- aha! --- Mr. King reconfigures his machine and now instead of smoke his new Flower-Fan sends out gusts of flower seeds. Working together, Mr. King and his friends use his new, smokeless machine to plant flowers, and Mr. King discovers that he not only likes flowers and machines, but caterpillars, too!
