Packed full of sliders, flaps, and so much silliness, this board book from Priddy Books will teach toddlers their colours through fun trivia. Do brown hens lay pineapples, do clowns drive red fire engines or do orange carrots grow on Mars? Each page features a simple question, with two fantastically silly false answers and one true answer, all hidden behind flaps and sliders that little ones can open and move themselves. This high level of interactivity, and the mixture of wacky illustrations and photographs will engage toddlers as they increase their vocabulary, and stimulate their imagination. Also available in the series: True or False? Words .
