Book Description: Snap! A day at the zoo can be lots of fun when you have a camera to catch the crocs, parrots, zebras, and other wild animals who live there. But what if your big sister is the photographer, and not you? Why, then you've got plenty of time to get into some mischief. But watch out! If you don't behave, the day may end early. Kids will especially enjoy the final picture, in which they have to try to find the feisty lead character.
