Blink, Zinc, Blip, and Zip comprise an unusual household of brightly colored robots in this charming rhyme. Each has his own special skill that makes him happy: cooking, repair, gardening, or cleaning. The robots grin through several pages of their daily tasks, framed by the refrain, “Hello, robots! Metal robots! Smiling bolt to bolt.” A rainstorm fries their robot brains, and suddenly the four can’t do their jobs correctly—the apple pie gets repaired, and the television gets planted. How best to fix the mix-up? Why, swapping robot heads, of course! After the switcheroo, the robots—now wearing one another’s contrasting-colored heads—can once again keep a lovely home, until they settle down for a tasty-looking afternoon tea. Chock-full of funny visual details (such as the pie baked on a backyard grill), with a thumping rhythm that makes this an excellent read-aloud. (Picture book. 3-7)
