Billy’s not like the other kids. He’s a bit moody a bit cranky a bit . . . grumpy. In hopes of cheering him up his mom takes him and his sister to the animal rescue one Saturday morning. All the animals are cute and playful but they’re a little too happy for Billy’s taste. When Billy wanders into another section of the store however he stumbles across a different group of animals awaiting adoption. These pets are grouchy and scruffy. In fact they seem downright grumpy—just like Billy! He catches the eye of a particularly grumpy pup—could this be the friend Billy has been looking for? Grumpy Pets shows that there’s a perfect match for everyone if you stay true to yourself.
