List of Crashes

Compiled here is a list of all currently known ways to intentionally crash the game. If one wants to play through and see as much as possible in the ROM Hack, they should be mindful of these events so as to not prematurely interrupt their play session.

Shadowy Figure
The Shadowy Figure entity appears in numerous locations throughout the game and, if not anticipated properly, will crash the player's game, usually after attacking or ambushing them in some manner. They are known to appear in the following locations:


 * Scary Sewer Maze: Approaching the figure sitting on a checkered floor amongst some blocks will cause it to grow in size before causing Mario or Luigi to take burning damage and then crash right after.
 * Wonderland Woods: The Shadowy Figure will pursue the player throughout the entire level, crashing the game upon contact.
 * Dead Village: After collecting the "5 secrets" star from the prior level and being sent to the dead village, the figure will slowly make its way towards the player, crashing the game when they reach them. This event only occurs for the "5 secrets" star, as any other stars collected in Bob-omb Village will return the player to the painting they entered from.
 * Nebula Lobby: In the upstairs area with labeled doors, door 1 is mysteriously blocked off with bricks, and approaching it will give an ominous message. If the Vanish Cap Switch has been activated beforehand, the player can open the Blue Block tucked away in a corner within one of the other numbered rooms and use their Intangibility to phase through the barrier. The Shadowy Figure awaits them on the other side along with its signature game crash.
 * Motos Factory: One of the rooms in the factory has a single white coin in a crack in the wall. Attempting to collect it seals off the factory behind Mario/Luigi and opens a new route that leads them to a room featuring Luigi's body repeatedly being crushed by a piston. Getting close to the piston will cause the Shadowy Figure to attack.

Mutant Toad
Notable for being one of the only recurring entities besides the aforementioned Shadowy Figure to appear in the Hack and antagonize Mario and Luigi, the Mutant Toad is a bizarre entity usually hidden away in very obscure corners of the game. He is always found in completely dark rooms as a semi-transparent, faceless Toad not unlike the ones found elsewhere in the hack, however upon approaching it will transform into its true form, a monstrous entity resembling a Chuckya made of several Toad faces. It can be encountered in the following locations:

In v1.0 and above, the Mutant Toad will kill the player instead. However, it will also permanently disconnect P1's controller, forcing a reset of the console.
 * Silent Sewers: Entering one of the doors and continuing through the repeating rooms will eventually lead the player to the Mutant Toad.
 * Unsettling Maze: The Mutant Toad can be found in a hidden passageway enshrouded in darkness, producing a constant, mechanical whirring sound. The cutscene and subsequent crash that occurs when approaching it here is identical to the one in Silent Sewers.

Faceless Mario
Like the Shadowy Figure, the Faceless Mario figures appear in numerous locations and in most cases will crash the game. The Faceless Mario clones encountered in Mario's Maze will not crash the game, instead causing instant death upon contact.
 * Cryptic Hideout: By entering the door from the right of Click Clock Climb the player can find a Faceless Mario standing far away in the void after a hallway. Getting closer to him will make several of his clones appear and attack the player, causing the game to crash in result.
 * Illusory Dark Labyrinth: Approaching the Core will cast everything in darkness and spawn a Faceless Mario to chase the player.
 * Crawly Cave: The Faceless Mario encountered here will not attack the player, though coming into contact with it will still crash the game.

The Core
The Core can be found in numerous locations including the AI Headquarters and AI Undergrounds where the player is instructed to "DESTROY IT". Hitting it in any way causes a crash.

Drowned Bro
The player may come across an unsettling variant of the courtyard known as the Fountain of Truth which rapidly flashes the text "IT HURTS" and "GET ME OUT" in an alternating fashion upon approaching the fountain. Rather than it being empty like it usually is, the fountain is now filled with blood, with the body of Luigi floating lifelessly within it. Approaching the body will cause the game to crash.

Lethal Lava Land's Wrath
If the player enters the Vanilla Basement at night, the music will change from the vanilla castle tune to the theme of Big Boo's Haunt. Entering the flooded painting section, there is a high chance for the face from the Lethal Lava Land painting to suddenly appearing and chase the player, crashing the game on contact. It should be noted that unlike most of the other crashes listed on this page, it is neither a softlock nor an unavoidable event. As long as the face does not touch the player, or simply plays the game during the day, the game will not crash and they can still go into any of the paintings as normal. One should take caution that the face's spawn location appears to be semi-random, and does not always spawn directly from the actual Lethal Lava Land painting (if at all).

Mr. I's Trap
Attempting to collect the star in Mr. I's Basement will suddenly teleport Mario/Luigi into an inescapable cage where they will be attacked by a giant Mr. I. Getting attacked by this Mr. I causes a crash.

White Coins
White coins have an extremely rare chance of appearing in place of regular coins and have a 25% chance of crashing the game when collected.

The Yellow Cap Switch (Pre-0.9)
In versions of the game prior to 0.9, approaching the Yellow Cap Switch in the Holy Yellow Switch Palace would freeze your game, effectively crashing it. This is no longer the case as of v0.9, as the Switch can now be pressed without impediment.

Nightmare Tower pipe
(0.9) A pipe can be found at the top of the Nightmare Tower, similar to the Dream Tower, but if the player tries to enter it, the game crashes.
