The Super Mario 64 Conspiracy Theory meme culture, often referred to as the 'SM64 Iceberg,' stems from the game's uncanny atmosphere and numerous urban legends like 'L is Real 2401.' It gained massive traction in 2020 through the 'Every copy of Super Mario 64 is personalized' creepypasta, which suggests the game uses an internal AI to adjust to each player's psyche. The meme usually employs distorted visuals, VHS-style filters, or the haunting 'Wario Apparition' head to evoke a sense of 90s-era 'liminal space' dread. It is widely used to joke about glitches, hidden secrets, or the nostalgic eeriness found within the halls of the Mushroom Kingdom.
