Each double page spread features movement when the pages are opened (or opened and closed since young audiences, be they on laps or in story time, will want to see the animation repeated). However, this gimmick is by far NOT the only thing to recommend this for a gift or for your library collection or just 'cause you want a book your little person will enjoy. The rhyming text by Boniface is nicely metered, short, and informative. "Nighttime's here, let's stretch and yawn. You'll sleep all night until the dawn. But while you dream til' morning breaks outside your door a world awakes"
Those double page spreads each show a creature of the night in its nightly doin's. "The cricket is a crafty critter When the sun sets, watch him skitter. Here he jumps and there he hops. While it's dark he never stops." And Milena Kirkova's illustrations most resemble Dav Pilkey ala "When Cats Dream" a bright (and yet NIGHT) mix of blocky heavy line cartoons and realism.
In addition to the regulars from animals-of-the-night books, they have chosen some different animals to present: Hippos, spiders, hedgehogs, and hamsters join wolves and raccoon and bats. And the final pages feature factlettes for older readers or listeners to enjoy. Comes as a hard back with the "animotion" movement or paperback with just glow-in-the-dark (That's the paperback in the image above; in the hardback the fox's eyes move). WELL worth the price of admission. Be ready for repeat readings no matter which edition you pick.
