Super Mario Negative One
A glitch in level 1-2 of the original Super Mario Bros allows you to take the warp pipes to World 0-1 and this is the level you get! It is basically a Bowser castle but underwater. The rub is that if you go the wrong way, you cannot back track and will have to reset (press F5).
