The world isn't just the way it is. All children have the right to play. Pi is a little boy who sees the world differently.
He sometimes feels as though the other children don't get him. He is a bit tired of playgrounds having the same boring slides, and he has always been longing for something exciting.
Mom and Dad arrive to see a hilly landscape, but Pi sees a set of saucers on a mountain and runs off in excitement. He spots the gentle, winding path where other adults are strolling, but forgoes it to climb the grassy hillside to see a field of large craters.
