Follow Wiggle and Waggle, two wormy best friends, through five squirmy chapters for beginning readers! These pals work hard in the garden, digging tunnels to keep the soil healthy and give the vegetables room to grow. It's a tough job, but everything is easier with a good song-and a good friend. Of course, all work and no play makes for a dull worm. Wiggle and Waggle love to swim and make mud pies for picnic fun! Young worm fans will dig the simple science facts included at the end of this charming book.
