Bum's the word! This humorous title delivers just what it promises: fauna fawning over their own rumps, no more and no less. Though scatological jokes would be an obvious extension of the theme, and scenes of creatures sitting down might be expected, Saito resists such content and mostly depicts the animals against white backgrounds, their backsides facing readers. The accompanying first-person text offers proud self-praise of the speakers' posteriors. At the very beginning, however, a hippo's head, rather than its bottom, peeks onto the recto facing a small rabbit, viewed from the rear, on the verso. The text above the rabbit boasts, "My bottom is such a round bottom--and so cute, don't you think?" The hippo replies, "I have a round bottom too! So round--and so-o-o big!" A page turn reveals that big bottom, and on the facing page an elephant looks down from the recto's upper-right corner to declare, "My bottom's even bigger! So much bigger!" The page turn reveals that yes, indeed, it is. Next come a tiger's, zebra's, and okapi's striped bums, then other colorful bottoms. Monkeys and baboons, shown front- and back-facing declare, "Our bottoms are the same color as our faces!" The culminating spreads show a lineup of every bottom from the prior pages. In Saito's delicate renderings, each bottom is distinct and, yes, beautiful. We like these butts, and we cannot lie! (Picture book. 2-6) Copyright (c) Kirkus Reviews, used with permission.

From the tiniest rabbit to the largest Asian elephant, animals have every reason to be proud of their bottoms. One by one or in groups, these animals turn their tails--striped, patterned, and boldly colored--toward the reader. Whether their bottom is heart-shaped like a deer's, fluffy like a sheep's, or spiky like a hedgehog's, each animal presents its wonderful bottom with pride. There's no story to speak of, but the bold and often iridescent-looking illustrations--using collage and featuring the traditional Japanese dying technique of bingata--are masterful, minimalist, and pop wonderfully off of the sparse white background. This off-beat book will appeal most to science-minded young ones, who will be fascinated by an angle of their animal friends they rarely get to see. Plus, it's fun to feature so many underrepresented animals. Where else but a children's picture book could an okapi, alpaca, armadillo, Malayan tapir, and Japanese macaque line up to boastfully present their posteriors?

A concept book (of sorts) about shapes, sizes, patterns, and animal traits is mostly an entertaining excuse to show a series of animal tushies -- beautifully illustrated in Saito's pencil collage, stenciled paintings, and dyed paper art. The double-page spreads feature plenty of white space and no background details -- the bottoms are front and center. Beginning with a bunny's petite derriere ("My bottom is such a round bottom -- and so cute, don't you think?"), viewers see a wide variety of creatures' backsides (Hippo's reply to Bunny: "I have a round bottom too. So round -- and so-o-o big!"). We see stripy butts (tiger, zebra, okapi), "heart-shaped bottoms" (deer), colorful creatures whose "bottoms are the same color as [their] faces" (Japanese macaque, mandrill), and more; a list at the end identifies the animals. The text is light, conversational, and funny; and the painterly patoots are lovely in their texture and shading. The grays especially are multi-toned and incorporate blends of blues, purples, reds, and pinks. A positive-body-image reading of the story isn't too much of a stretch; by the end (ha!) we've learned a little about these remarkable creatures, as the text concludes: "Everyone's proud of their bottoms! Such wonderful bottoms -- each and every one!" Elissa Gershowitz September/October 2020 p.73(c) Copyright 2020. The Horn Book, Inc., a wholly owned subsidiary of Media Source, Inc.
