On every beach,
where a sand castle lies,
there is a real kingdom below
that sits in disguise.

From a royal king crab, to a majestic whale, to a beautiful mermaid, little ones will love lifting the die-cut flaps on each spread to reveal the ocean creatures living inside each castle. Shaped like a sand castle filled with fun underwater details on each page, this lift-the-flap board book is the perfect summer read-aloud.
