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.
