On a picnic with their parents, Bluey, Snickers and Coco play Shadowlands – a game where they must only walk in the shady areas and avoid the crocodile infested, sunlit grass.

But Bluey finds that every time the game gets too difficult, Coco tries to take a shortcut. Finding themselves stranded in a palm tree shadow-island when Mum calls them back for tea and cupcakes, Coco is ready to break the rules and step out of the shade.
