Excited, Squeeks wants to go and look for this creature, and when Daisy and Hal want to join her, Nature Cat knows that his worst nightmare has just come true! / When challenged by Ronald to compete against him for the Neighborhood Rock-Skipping Championship of the World, Nature Cat confidently accepts.
