well lok at when he opened it.. it was at solid gold. or birght thin..(the question marks) and when you do that you get the teddy bear which causees it to float and eventualy disapear. so i think it was that
whenever u try for a weapon in the mystery box u can get a teddy bear and the teddy bear means the mystery box will move anywhere on the map and when it changes it flies up in the air and then disappears and goes somewhere new on the map!!!!!!!!!!
