The favorite game of toddlers gets a dino twist. A large dinosaur tries to outsmart a smaller companion when the duo play peekaboo together. The big dino naïvely believes they won't be noticed behind or under sundry hiding places, but the little pal always finds their playmate. Young listeners will giggle as the large dino attempts to outwit the little one, but in vain; in every instance, the diminutive, overalls-clad dino calls out a triumphant "Peekaboo!" How come? Is it because thin tree trunks and a potted plant can't conceal the large dino's frame? Do the big dino's bold, flower-print shirts stick out a mile? Even when the large dinosaur attempts an aerial hiding place, they discover that ruse doesn't, ahem, fly, nor does hiding in a crowd wearing a Where's Waldo?--esque red-striped cap and T-shirt do any good. In a display of good sportsmanship, the big dino concedes at the end the game was fun. The youngest audiences, all of whom will have likely engaged in marathon peekaboo sessions themselves, will undoubtedly scramble to play again. Besides stimulating playtime, this adorable board book, expressed in lilting rhymes, boosts vocabulary development through the use of some common prepositions (behind, in) and adverbs (here, there, everywhere). The illustrations are sweetly engaging; the round cutout on the front cover invites youngsters to play peekaboo games with adult partners and others. (This book was reviewed digitally.)
