Fiona digs, builds, and pretends in her favorite spot—the sandbox—in this second of four irresistible full-length miniature picture books, where the littlest readers are introduced to new friends and the charming world of the Hippo Park playground.

Fiona is a builder and a digger, and has a big imagination. She’s digging for dinosaurs when she hits an imaginary bone and poof–she and her brother Herbert are face to face with a dino. So naturally, they bake cakes and pies and enjoy!
