Monsters Play...Hide & Seek! by Flavia Z. Drago

From Candlewick Press:

Come out, come out, wherever you are! A monstrously sweet lift-the-flap book from the acclaimed creator of Gustavo, the Shy Ghost is perfect for Halloween—or any day.

Buster and Gustavo
are playing hide-and-seek.
On the count of five . . .
Buster will hide!

One, two, three, four, five! Buster, are you hiding behind the plant pots? No, it’s Jack O’Lantern, watering his mandrakes! Are you hiding under the bed? No, it’s Max the monster, looking for his lost yellow sock! Kids will happily lift the flaps to peek in the window, look in the shower, open the closet, or spy in the fridge and be surprised by friendly characters going about their day. With a fun interactive element and bright, cheery illustrations, Flavia Z. Drago weaves in cameos by characters from prior books to make this a memorable game of hide-and-seek for old fans and new friends.
