Laugh-out-loud nonsense poetry combine with cutting-edge paper collages for an irresistible picture book. Hort, familiar to readers as the author of the far more sober Reading Rainbow selection How Many Stars in the Sky? (1991) here reveals his wacky, endearing side. This book should come with a disclaimer: “Warning: Regular classroom read-alouds from this perky collection of 18 poems could cause a room full of second graders to dissolve into uncontrollable giggles.” And who could resist “When Groundhog Slides Down the Chimney,” which reminds readers that it’s time to “carve your eggs and paint your pumpkins” as “Columbus, it will soon be Christmas!” Beware—if you’re trying to soothe little ones before bed, do not read “Lullaby,” which urges kids to first “open your eyes” and then “close your eyes, it’s time to wake. . . . Come taste your breakfast rattlesnake.” Readers will enjoy the delicious “Broccoli Pie” and the “peppery cool / and lemony sweet” taste of “A Pair of Purple Oranges.” “I Drove Over Oceans,” with its pleasing echo of the old jump rope favorite “Johnny over the ocean, Johnny over the sea . . .” could sweep 21st-century playgrounds. Kids and teachers may be inspired to try their own hands at nonsense verse. But caution is recommended. Kids might find these poems too sidesplitting to settle down and write. Kroninger’s bright and wacky cut-paper collages vibrate with energy. Incorporating eye-popping magazine photo images, they fairly burst from the pages and never fail to ratchet up the hilarity.
