This is the show you put on when your nervous system needs a nap. Rocky doesn't save the world, he just takes whatever daydream Amy happens to be having and quietly makes it real, then blinks at you like he has no idea he did anything special. That's the whole trick: he has no clue his powers are worth anything, so nothing ever curdles into a lesson or a stakes-raising villain. The lunar cat thing never gets confirmed, either. Somebody says it, the show shrugs, and 170 episodes go by without a single origin flashback, which is honestly more discipline than most series manage. At a few minutes an episode it's built for the gap between things, and the part-cat-part-raccoon design does more heavy lifting than any dialogue. You watch four in a row and feel like you got away with something.
Amy heads off on a camping trip with her family. Along the way she finds Rocky tucked in her backpack among the gear: an odd little creature that seems part cat and part raccoon, and whose origins nobody can explain. Rocky decides Amy must be his sister and trails after her wherever she goes. He also holds a special power he barely understands, the ability to make the fantasies of children come true. Amy is lively and curious but quick to lose patience with the world around her, and Rocky's arrival turns her life upside down as he transforms her dreams into real adventures. His intentions are always good, yet his magic sometimes misfires and nearly ends in disaster. Through the ups and downs, the two become an inseparable pair in a lighthearted comedy fantasy told in short episodes.
