Mr. Rally and his dog, Lightning, both like digging in the dirt. And when Mr. Rally goes to work in his yellow backhoe, Lightning comes along. Today they have five jobs: hauling rocks for the bridge on the ridge, digging a drain for the rain, moving a load on the road, digging a hole for the pool at the school, and leveling the ground for the brand-new zoo. There is a mix of rhymed and unrhymed text in this appealingly busy board book that briefly details the work on each job, always ending with the same refrain: “Dig up rock and dig up clay! Dig up dirt and dig all day!” This is followed by a question: “Is the digging done? No!” Rhyming, construction equipment, and the invitation to join right in — what’s not to love? The inviting illustrations offer plenty of detail without the small board pages feeling cluttered. (Ages 1–4)
