Here's how to get the Picto box. First go to the town jail on Windfall Island and let Tingle out.
He will give you the tingle chart and the Incredible chart and will leave.
After he has gone go into the cell and smash the crate. You will find a hole in the wall.
Crawl into the hole and follow these instructions. Always go forwards and if you can't go right.
Eventually you will come to a room with a chest in it. Open the chest and you have found the Picto box!
