A sweetly anthropomorphic Rhino family learns to appreciate their child’s unique interests through surprising support from an unexpected source. Bud Sweet-William is a mystery to his staid parents. They are “proper, sensible” and preternaturally neat. Bud has adored dirt since he was a toddler. While they prefer tidy silk flower arrangements and counsel Bud to color inside the lines, the ebullient Bud likes to “cut loose” when he paints. He is happiest digging, composting, and growing a backyard garden and reveling in the growing jungle of indoor plants that are rapidly over-running his room. Carefully cultivated family equilibrium is soon threatened by a visit from Bud’s paternal grandfather—a neatnick of the first order. How to keep Grandfather away from and unaware of Bud’s gardening? Upon arrival, Grandfather takes charge. He gives the house a thorough cleaning and reorganizing (even the canned goods in alphabetical order). A violent overnight thunderstorm wreaks havoc in Bud’s garden. When grandfather and grandson survey the remains the next morning, Bud learns that far from being dismayed, Grandfather is instead impressed with the garden and organizes its cleanup. Author-illustrator O’Malley’s (Leo Cockroach . . . Toy Tester, not reviewed, etc.) well-sized, sweet-natured, cartoony watercolors are full of the right kid pleasing details that add to the low-key fun. A delightful springboard for budding gardeners and an opportunity to share their enthusiasm with family and friends. (Picture book. 5-8)
