A blue butterfly, red rooster, purple parrot and pink pig are joined by a bevy of other fancifully colored animals in a run along a rainy beach that culminates (rather inexplicably) in a frolic under the sun. Inset into each animal is a raindrop-shaped cutout that contains a sheet of clear, colored plastic; when layered over one another, they combine to make the appropriate color—so when kids turn the page, the yellow yak’s raindrop overlays the red robin’s to make the orange octopus. The line-up of animals is punctuated by long shots of them all scampering through the rain (“GO! GO! GO!”) and then playing in the sun. If the plot isn't much, Garofoli's playful, big-bellied critters—most accessorized fetchingly—will charm readers. Fun, with a little subtle instruction on color mixing. (Board book. 1-3)
