Publisher Annotation: No one likes getting caught out in the rain! One drizzly day on the farm, a cow overhears a cat meowing to be let into the house. When the kind old lady inside opens the door, the cow gets an idea--one that spirals out of control!

After helping the Greenstalk family get to the county fair, the cows busy themselves finding solutions to many other problems that arise during the day.

Albert Hopper, Science Hero is on a mission: to travel to the center of the earth! With his wormlike ship Wiggles and the help of his niece and nephew, trusty Junior Science Heroes Polly and Tad, Hopper is ready to go where no frog has gone before. Thick layers of rock and rubble, tunnels of lava, and temperatures of 6,000 degrees stand between our heroes and their prize. Will they make it?
