Each totable tower contains ten chunky, stackable books with simple text and endearing illustrations. Parents can read the books with their child, build with them like blocks, and then slip them back into the tote-along tower for on-the-go fun and learning. Each book features playful rhyme about a different sea creature. As they read along with the ten stories, kids explore the wonderful world under the sea. Book Titles: clown fish, crab, dolphin, octopus, seal, sea star, sea turtle, shark, stingray, and whale.
