In the final area of Minefield Mishap, you are supposed to carefully walk through a maze of mines to reach a golden staff. This entire maze can be skipped. After taking the last teleporter, you see the staff item on your characters right. You need to collect this in order to complete the challenge. If you walk directly towards the staff and into the first mine on your characters right, you can push and walk through the gap before the mine replaces itself. You'll get knocked back and take damage, but the mine wall wont replace the detonated mine before you walk through again. This is especially easy for characters with a dash move.
