What happens when a moose--and other animals--have a mustache? "When a moose has a mustache, it wiggles when they walk." "When a toad has a mustache, it tickles when they hop." "When a bear has a mustache, it stands straight when they growl." "When a coyote has a mustache, it droops down when they prowl." This oversized board book with gatefolds is a silly story of forest animals sporting different mustaches. Kids will love to see the anthropomorphized animals, including a moose with a hiking stick, a toad with a fishing pole, a coyote catching fireflies in a jar, and a mouse roasting marshmallows over the campfire. Sam Caldwell's playful, stylized, and vibrant illustrations bring the characters and humor to life.
