The Boy - Mysterious Island 1

Once, there was a teenager named John. He lived near the sea in a huge building. There was also an island not too far away. One day when he went to the sea, he heard some weird noises coming from the island. He went there and saw that there was a robot who was huge and was digging a hole.
