There is so much "win" about this book.
I bought this book from the Kohl's Cares campaign, so I got a fabulous hardbound book by Mercer Mayer for $5, and I was buying for a good cause, and my five-year-old son not only loses things, like his shoes, but also loves Mercer Mayer.
At the time I bought this book, I didn't realize it was a lift-the-flap book -- that means more Mercer Mayer art and more "win".
The story itself, of course, is adorable and completely relatable to preschoolers and early elementary school students. The illustrations, of course, are even more adorable and relatable and I love, love, love the frog.
