This anomaly appeared as a Super Mario 64 legend, in a level featuring water. Once the Textureless Mario Anomaly activates, Mario's model will change into a faceless Mario, and the water textures will go invisible. Interacting with objects during this glitch will cause the game to crash. In some personalized copies, an error message will appear along with several faceless Mario heads on the bottom part of the screen. Any music and sound effect in the game will cease if the anomaly is active.
