When you have confronted the box that pop's up out of the ground that block's your way, Inside the box is a puzzle where you must make your mouse reach the block of cheese. The easy way to get through this puzzle is follow the way the mouse (in the puzzle) is looking, for example if there is two doors on your right and left and the mouse is pointing right go in the door to to the right! let's say there is two doors to right, you have to go between the two doors and whichever way the mouse is pointing, go in that door. Hope this helps!
