Take a walk on the wild side and prepare to be entertained by the shenanigans of critters around the globe. Step into the fascinating world of animal playtime to find penguins surfing for the joy of it, primates playing peekaboo, and sneaky keas--the pranksters of the bird world--yanking one another's legs just for kicks. Creatures of all stripes like to play! Some play builds strength and teaches survival skills: a game of tug-of-war prepares wolf cubs for hunting and taking down prey, while games of hide-and-seek give mongooses practice at quick escapes, handy for outmaneuvering predators. Some games appear to be played simply for enjoyment: Polar bears love to slide down snowy hills, then climb back up and do it again. Gorilla parents swing, hug, and give bouncy rides to their children. And elephants have been known to lie in wait for a companion to come strolling along, then--BAROOM!--roll downhill to bowl them over like a friendly ball. Join Richard Haynes and Stephanie Laberis, creators of Orangutan Hats and Other Tools Animals Use, for another illuminating walk on the wild side. Scientific observations from the natural world, a glossary, and a bibliography combine with colorful and vivacious illustrations to make this guide an extra fun look at--fun!
