★ ”You better watch out for this excellent early reader.” –Kirkus Reviews, starred review
★ “Barnett works wonders with a limited vocabulary, packing the stories with humor, tension—and admonishments of Jack. Pizzoli’s scruffy-edged, emotive cartoons are just as funny, and he carries the comedy into drawing lessons and closing endpapers.” –Publishers Weekly, starred review
★ ”Jack is a rule-proof bundle of bunny-eared id who does as he pleases, and therein lies his considerable charm.” –BCCB, starred review
