As her name suggests, Itty Bitty Betty Blob is a small, amorphous monster, but that's not what sets her apart.It's Betty's cheerful demeanor that makes her different from her peers. What kind of monster "rejoice[s] at rainbows" and "dance[s] among the dandelions"? Betty's pink hue also distinguishes her from her classmates, who are rendered in a black-and-white palette, and makes her stand out in her rather somber, expressionistic setting. Brief, alliterative sentences keep the pages turning as readers learn about her trouble fitting in at school: While the other students faithfully reproduce a still life of dead flowers on a table, hers is a vibrant image of a living, yellow daisy. The crisis comes to a head on picture day. Despite the dreadful outfit her mother selects, Betty can't grimace fiercely enough. As she travels through the spooky forest to school, the diminutive monster is distracted by a pink puff. Following it, she encounters an entire fluffy community that encourages her to be true to herself. Her frightful frock becomes an extravaganza of flowers. The climax involves a mood transformation for the entire class as puffs emerge from Betty's dress, tickling everyone as the flash goes off. Children will enjoy the humor in the reversal of expectations around classroom culture-and will be heartened by Betty's willingness to embrace what makes her different-although subsequent readings don't yield much more.A light touch delivers an increasingly common but important message.
