Bang, Bang! Who's There? — Karen Jones

They're small but chunky board books -- and they're guaranteed to fascinate toddlers with their moving animal illustrations that present charming visual surprises. Each two-page spread has a "who's there?" question and a peephole showing a pair of animal eyes. Kids place a finger into a slot cut into each illustration, give a little push, and out pops the complete animal. There are six pop-out surprises in every book, and the brightly colored cartoon-style animals who come popping out will delight little boys and girls. Toddlers wake this turtle up when they bang on his shell. His head and feet pop out! Five more amusing creatures come to life on following pages. (Ages 1-4)
