Slasher's adventure

Slasher was bored one day. He tried to impress himself with a few tricks Kalim taught him, but that didn't help. He visited Winddershadow, Sunbeam, and Shadowmal, but that didn't help either. Then he remembered something. "Hey! I haven't been on an adventure for 2 weeks now! I should go on an adventure!" He said. He summoned his crew and sailed off to the Mysterious Island. It was a small island. They dug to see if there was treasure, and there was 4 of them. They found another treasure chest on the same island at their first adventure. Then they found 10. The numbers increased. Slasher was counting the chest. "19, 20, 21, 28, 36..." More treasure chest piled up, and Slasher counted them all. There was..."59 chest!" He screamed. They put all the treasure chest on their ship, the S.S. Seadragon Wave. The ship was sinking. They put 29 chest buried in the island. The ship started floating again. They sailed off to Dragmori's Main Island. Everyone saw the treasure chest they had. "Wow! You found all that treasure in one adventure?!" Said Kalim. "No."Replied the crew. "We've found 59."
