รายละเอียด(อย่างย่อ) Eric Carle's familiar illustrations of brown bear, red bird, yellow duck and the other endearing animals from his classic creation parade across the pages of this great interactive board book. As each page is turned, a new animal and its color are introduced, accompanied by Bill Martin's singsong, rhyming question-and-response text to read aloud or listen to. There are sliding doors throughout the book, which children will just love to open, so they can discover what the next animal in this engaging story will be.
