This is a very short level. The player starts in front of a cannon. Mario needs to enter the cannon and a countdown will initiate. Mario will then be shot to a night world where he needs to jump and avoid the enemies and falling into the gaps. One can collect all the coins along the way if the player wishes. Mario will continue to dash until the end of the level, so it is essential that he jumps at the right time. The only enemies here are Koopa Paratroopas. A Red Ring can also be found in the level.
