When Mr. King the cat discovers that one of the pretty flowers near his home has been chewed by a caterpillar, he is NOT happy. He decides to build himself a Caterpillar-Catcher to track down the culprit who did it. ?VOOM! VOOM! VOOM!? But as he speeds up and down the hillsides, Mr. King doesn't notice that the Caterpillar-Catcher is spewing nasty smoke into the air and knocking down the other pretty flowers in his path. Now it's his animal friends who are NOT happy. They explain to Mr. King that his machine is making things worse, not better. And why chase a caterpillar anyway? Caterpillars turn into butterflies, and butterflies help the flowers to grow! Will Mr. King be able to turn things around so everyone will be happy again?
