"Fluffy fun that promotes visual literacy and will make a positive addition to interactive storytime collections." —School Library Journal   "Santoso's art conveys broadly comical action, and his slightly retro palette and exaggerated cartoon style are well-suited to the undercover prowess Spy Guy seeks." —Kirkus   "Santoso’s crisp images and liberal use of white space keep the focus on domestic comedy...but it quickly turns into a tribute to savvy parental mentoring." —Publishers Weekly   "Santoso's wonderfully noirish illustrations make this book fun and engaging, as do Young's rhyme schemes and wordplay." —Booklist —
