Mouse's birthday is here, and all of his friends are planning a party. Don't tell Mouse, though. It's a surprise! With the unique Flip-Flap construction of this charmingly chunky board book, little readers peel back overlapping pages as the party unfolds—literally! Add to that some bright and friendly watercolor illustrations, and a dose of extra-sturdy construction, and Happy Birthday, Mouse! is one preschool story that's definitely worth celebrating.
