In the vein of Grumpy Monkey and Unicorns Are the Worst!, this hilarious picture book introduces the adorable quokka, who—despite his ever-present smile—is definitely not as happy as he looks!

With its bright eyes, puffy cheeks, and beaming smile, the quokka is clearly the happiest animal on earth. Or is it? This quokka is here to tell you…he is not happy! At least not all the time. Just like everyone else, he can be sulky, or sorry, or sad; but you’d never know from the look on his face! So, what’s a moody marsupial to do when he’s being misunderstood? Teach every other animal from kangaroos to koalas not to judge a critter by its cover!
