Journey follows the adventures of Saben, a young boy who is suddenly awoken from his sleep in the middle of the night. He’s alarmed to see he has shrunk down to size, and perhaps even more surprising is that one of his favorite toys is alive and talking, urging Saben to follow him to safety, but in the urgency a clear explanation isn’t given. Saben is caught up in an adventure that sends him across a vast civilization of sentient toys that exist under the radar of the world around them. Saben must figure out the mystery of the toys’ sentience and get himself to return to his regular size.
