Bowser’s fortress

Bowser's Fortress, with its multiple rooms and passages, is the final location to be scrapped. It is also the last scrapped level to be fully explored for the game. However, It is only the second to be included as Deleted bowser levels. It’s the closest to a proper dungeon to date. A great dungeon, in my opinion, if you're not a huge fan of having to run from all types of traps. This level was the last dungeon to go through, as it is also the only level to ever require a special bowler's level. In addition, it was also the last dungeon to have a secret room at the end. This level could be found on the level 4 map. The only other place to find it is in the final level (where you meet with the other players at night to discuss strategy), which is also the last one to be fully explored.
