The ground is all white and cold, and Squirrel has no idea whyAwakening to find the grass is gone, Squirrel panics and calls for Bird. Ever patient Bird explains that sometimes it snows in winter, and the grass just gets covered. Bird suggests they play in the snow, but Squirrel says it's too cold…until Bird introduces Squirrel to snowballs. Suddenly, Squirrel loves snow. Bird also explains that snowflakes are all different shapes. Squirrel's skeptical. "They're all small, white blobs." Then Squirrel yells, "BIRD! There is SMOKE coming out of my mouth! Is it because I ate a snowflake?" Bird notes that sometimes it gets so cold that you can see your breath. A frozen puddle sends Squirrel sliding into a giant snow squirrel. Squirrel's pretty sure that snow squirrel stole some hazelnuts. Bird explains that's impossible: "It isn't real-it's just a SNOW squirrel." When the snow melts overnight, Squirrel is convinced the snow squirrel took it all-but at least the hazelnuts are still there (the builder of the snow squirrel had used them for the eyes and mouth). Hemming's tale, which relies on speech bubbles and text in several different fonts for emphasis (and overreaction), is as funny as the first two in the series, while Slater's digitally created, colorful illustrations add some slapstick giggles. The book finishes with a double-page spread of snow facts that address Squirrel's concerns.May this endearing pair have more sneakily educational outings.(Picture book. 2-7)
