It's the wee morning hours, and Carter the Caterpillar is wide awake and bored. To liven things up, he decides to explore a big house where everyone's asleep, and once inside, can't resist going on a tickling rampage. As he moves from room to room, every family member--mom, dad, grandma, grandpa, brother, and sister--encounter the mischievous caterpillar, who tickles most all of them both high and low, from ears to toes, gleefully giggling. After Carter's exertions caused him to fall asleep on the kitchen counter, he wakes up to see six smiling people ready to do some tickling of their own. This beautifully illustrated picture book is as perfect for story time as it is for bedtime. Children will delight in Carter's antics and everyone will love to join in the refrain: "It's tickle time!"
