Level synopsis
A level similar to that of the battleship level in Dark Land, the player has to cross over various maritime ships until the player comes to a dock. The player has to choose whether to pick the high route or the low route. The low route leads to a tiny ship at a dock with a pipe, while the high route has the player access a much larger ship from a catwalk above. Depending on the choice, the player can either fight Ludwig von Koopa and defeat him easily with one stomp on a level playing field, or fight him in a contained, uneven area with the usual three stomps to defeat him, respectively. In either case, the player has to fight Ludwig.
