Mr. Rally and his faithful dog, Lightning, have a busy day ahead of them, but they don't mind. What could be more fun than using a big yellow backhoe to build a pool at the school and a drain for the rain? You can follow Mr. Rally through his day as he travels around town, counting from one to five in an irresistible refrain. Marc Rosenthal's colourful, nostalgic illustrations add a bold dimension to the lively text by the husband-and-wife team of Andrea Zimmerman and David Clemesha. Dig on, Mr. Rally! Dig on, Lightning!
