Wario Apparition

The Wario Apparition is an anomaly seen in certain personalized copies of Super Mario 64. It is often characterized as a large Wario head appearing in the castle basement's Dire, Dire Docks hall. When it appears, it is advised to turn off your console immediately, as it can cause the victim to experience stroke-like symptoms when attempting to describe the Wario Apparition. It will say "You want fun? Wario show you fun!" when approached, and begin to chase the player down the now endless hallway. If caught, the player will be presented a game over screen regardless of how many lives they had before. Upon being chased, the endless stairs theme will play. It also has a connection to the Wario Application.

Boss Battle
Some people have reported exiting the hall and ending up in the main room of the castle's first floor. Upon entering it, a boss theme will play (one report of the boss fight theme can be found here, uploaded by Planet Bobstar) and the Wario Apparition will appear, and a boss fight will begin. It usually attacks by charging the player, and shooting fireballs. It is extremely hard to avoid. It is defeated by ground pounding it's head 3 times, though getting on top of it is extremely hard to accomplish. Upon defeat, the player can usually unlock Wario as a playable character.

Painting
Some people have reported finding a painting of the Wario Apparition, that when entered, will lead to either the hallway chase or the boss fight. It is currently unknown as to why this painting appears, as there is already a way to find the Wario Apparition. It is possible that similar to the DS remake's character levels, it was intended to be found to begin the fight. According to a few reports, the painting changed to show their prior experience with the Wario Apparition if they encountered it before finding the painting.

Scams
For some reason, several scams have been made similar to the "DO NOT DO THIS AT 3 AM" challenges on Youtube. These are the currently documented scams:

Potion
It is a yellow potion. If you find this, you should not drink it, as it can contain poison or drugs.

Happy Meal
No information has been found on this scam yet.

Phone Call
There is a supposed number that when called, can summon the Wario Apparition. It is currently unknown if this is correct, but it is recommended not to, for your own safety.

Pill
At one point, the police found Wario-shaped tablets of drugs that were confiscated. It is unknown if these are related to the scams, but will be grouped with them due to their similar nature.
