Book excerpt: Two fuzzy creatures are happily putting the finishing touches on their sandcastle when each of them thinks of something that would make it even better. As they work furiously to incorporate each new change, their tiny sandcastle becomes an over-the-top palace...but is it really perfect? This latest book in the beloved series featuring the pals from Theodor Seuss Geisel Award winner You Are (Not) Small reminds us that perfection is in the eye--and heart--of the beholder.
