Curly the Pig, by Usborne Books, is a story about a little pig who escapes from his pig pen. A little girl and her dog search for him everywhere before finally finding him.
On each page of the book is hidden a small rubber ducky. My daughter loves to go through the book and find the ducks. In fact, this is the best thing about this book, as the story is very short and not very interesting.
The illustrations are nice. We have the board version of this book, and it's held up well despite my daughter's chewing on it (the fact that she wants to chew on it rather than read it speaks volumes with regard to the story).
Like most other Usborne books for kids this age, I would not recommend this book.
