First of all, how many board books that you know give you the chance to 'Choose a Dino?' This one does. You get to pick the picture of the dino from the menu of tabs on the right side of the book and then when you open to that page, you read about that dino. Some dinos are asleep, some have horns and some even have ice cream cones. My favorite is 'Hey-Ho-Howdy.! He's a lively fellow who 'is always happy. He stands out in a crowd'.But sometimes you wish he would just go away.' Hilarious. When you turn the page and make him go away, you can meet Sob. He's a bit of an Eeyore and when you get tired of him you can try'.Oh, I'm not going to tell you. You'll have to turn the page yourself!
