|Treasure chest full of coins, jewels, pearls.. Once part of a mighty Forty Thieves treasure collection. Sadly, this is all that remains of the Thieves past exploits.|
— In-game description[src]
It is a wooden treasure chest that is open slightly, due to it being unlocked with a large key sticking out of the lock.
In the southern portion of the map on top of a building is a laser floor. Use the Jailbird Costume to cross the floor and press the button. Swing across the gap using the hook, then use the Samurai Costume to deflect the fireball back at the costume door. You now have 40 seconds to get the treasure back to the safe house.
