Go to the pirates lobby, and take the exit on the far left to get to the Treasure Room. The three different keys you've earned correspond to the three different treasure chests there! Each chest has items you can win, and they switch out every month! One of the rare prizes this month is the Stitch Backpack, which can only be won from the gold chest. You can see a picture of all the prizes on the newsletter! Does that answer your question?
