OBTAINMENT: The location is a button that is VERY, VERY hidden. Once the button is pressed, it will ask a few questions. If you answer them correctly, BOX=FALSE will appear and give you a boss fight. The boss fight is incredibly simple: just move your cursor to dodge his attacks. After the boss fight, you get him.
HINT: “WARNING: YOU MAY NOT PROCEED IN YOUR BOX COLLECTING!” DESC: “WARNING: YOU MAY NOT PROCEED IN YOUR BOX COLLECTING!” Idk the difficulty. The difficulty would be more harder (NOT THE DIFFICULTY CALLED HARDER) due to the lack of hints.
