Can kindness be catchingThe Yowler family consists of pointy-eared, sharp-toothed, horned monsters who are terminally glum. In fact, "at the Yowlers' house, grumpiness [is] a way of life." Text full of alliteration and gentle humor describes various mildly troublesome situations that arise. Whether the family is attempting to garden, clean up, or go shopping, things end with inevitable grumbling, brawling, shrieking-and messes. Until, that is, some brown-skinned human neighbors move in next door. Appropriately named the Nicelys, they're friendly and helpful and do strange things with their teeth (readers will realize they're smiling)-whatever can this mean? The Yowlers find themselves reconsidering their grumpy way of life and begin to display more positive traits, including resilience and consideration, and soon they're even smiling. By the end of the story, their pointy ears, sharp teeth, and horns are a distant memory, and the Yowlers are depicted as light-skinned humans. As a tool for social-emotional learning, this somewhat didactic tale verges on oversimplification but clearly states its explicit message about kindness in terms kids will easily understand. Funny, action-filled illustrations reminiscent of Mercer Mayer's work round out this lesson in positivity.A preachy but upbeat antidote to grumpiness.(PIcture book. 3-6)
