รายละเอียด(อย่างย่อ) All of the animals in the train are going to the zoo—one elephant, two hippos, three giraffes, all the way up to ten birds! Eric Carle’s classic counting book has never been so much fun. Kids will love to color their favorite animals and complete the activities on every page. They can unfold the back cover to see the animals play at the zoo and to practice their counting.
