Castle Calamity

 is a flash video on Newgrounds which consists of Mario trying and failing to blow up a castle, with his plans always backfiring.

In M.U.G.E.N,  has been made once by N-Mario, where it is a bonus game.

Gameplay
Castle Calamity cannot be controlled by the player, as it is a bonus game. However, the player can push the Enter key to start the game.

The intro consists of the character the player is controlling going on a stroll minding his/her own buisness when suddenly, a castle falls, surprising the character. The character does his/her taunt, and then, the game begins. The objective is to try to destroy the castle, though the castle takes no damage from attacks. The castle starts by moving away from the player once he/she gets close, and then the player has to do something like push a switch, hitting a ? block, and so on. However, just like the flash video itself, the plans always backfire, and the player always ends up getting hurt by the castle.

N-Mario's objectives include:


 * 1: Running towards the castle, only for it to move away


 * 2: Detonating a fuse that either goes farther than the castle, setting the player ablaze, rocketing them towards the sky, or summoning a Banzai Bill


 * 3: Using a Crouching attack on the Castle, forcing it to topple over them


 * 4: Hitting a big blue switch with a "!" on it that transports the player to the "Adventure" game on the Atari


 * 5: Hitting a Smaller "!" switch that removes the floor


 * 6: Running at the Castle again, only to slam face-first into it, then explode.
