Harold and Hog aspire to be Elephant and Piggie, of Mo Willems fame, in a game of pretend, with the aid of a Piggie-like nose for Hog and round glasses, like Gerald the elephant’s, for Harold. The only problem? Where Piggie is carefree, Hog is careful; and where Gerald the elephant is careful, Harold is carefree. But if they can’t be Elephant and Piggie, can they still be best friends? With similar speech bubble dialogue and art featuring an elephant and pig (or hog) with slightly sharper edges, the relationship between this playful, raucous parallel and Willems’s original is as funny and warm as the relationship between Harold and Hog—and Elephant and Piggie.
