Bluey and Chilli are on a picnic with two other moms and their kids, Coco and Snickers. The kids are playing a game and get a bit frustrated after Coco just seems to bend the rules perfectly to win and get what she wants. So the kids switch to playing Shadowlands and Snickers and Bluey try to keep Coco from bending the rules. But cupcakes will test EVERYTHING as the kids learn about how following the rules can actually make games more fun!
