Silly Tilly is the farm comedian, entertaining all the animals with her goosey, goofy behavior. “She wore a pancake as a hat. / She tried to ride the farmer’s cat. / She kissed a fish. Imagine that!” But sometime after she sits on and squashes Rooster’s birthday cake, the other farmyard animals get fed up and tell Tilly Goose to end all her silliness: “No more naps in Scarecrow’s pants! / No packing piglet off to France. / No yodels at the Harvest Dance!” Weeks later, a very quiet and sedate farm has stopped laughing. “It’s dullsville on the farm. No fun!” Apologies are expressed “with quacks and oinks and heartfelt sighs,” and soon Silly Tilly’s back to her foolishness and the much-missed jovial atmosphere is restored. Slonim’s expressive cartoon-style paintings rendered in acrylic, pencil and ballpoint pen on linen actively complement Spinelli’s humorous triads, reveling in the ridiculous absurdity. A surefire hit for storytime and shared reading sessions. (Picture book. 3-6)
