The animation does what Ghibli does, it makes you forget you're watching instead of living in the world. A kid rescues what he thinks is a hurt animal, and it opens into a summer that feels like stepping into a dream you didn't know you were having. The pacing sags in the second half, but by then you're too deep in the spell to care.
Five kids arrive at a remote mountain camp expecting a lazy summer away from adults. Their plans for quiet days in nature derail when they rescue what looks like an injured puppy, only to discover their new friend is actually an alien named Pochi. The creature isn't lost on Earth by accident. Pochi came searching for a mysterious substance scattered across the planet that countless alien species want to exploit, and a brutal conflict over it nearly killed him. Grateful for the kids' help, Pochi decides to reward them in spectacular fashion: an all-expenses-paid tour of the galaxy. What starts as a summer adventure transforms into something far grander as these five ordinary children are thrust into an intergalactic playground. They'll encounter bizarre alien cultures, navigate cosmic mysteries, and discover that the real treasure isn't material at all. The film balances genuine wonder and humor with moments of genuine danger, creating a space opera that never forgets the joy of friendship. It's a story about how helping a stranger can open doors to worlds you never imagined existed.
