The artist who created this extra-thick book of zany animal pictures has left out at least one important detail in every illustration. It's up to boys and girls to discover the missing element, then pick up their pen or pencil and start doodling. Kids are free to draw any new detail that they please as they try to make each funny picture even funnier. Silly snakes, madcap monkeys, frolicsome fish, as well as dogs, cats, and more than a hundred other animals are here in cleverly silly pictures for kids to complete.
