Notexture is an entity with the ability to teleport the player to Day A or bring the player's health to half a heart. It is seemingly intentionally hostile to a certain degree. There is little more information on it other than what is known of its behaviour.
¶ Appearance
Notexture is a player-sized entity with a fractured head - one quarter of it is missing, and half of it is grown into a branching, antler-like structure. Its entire body is missing textures, with the usual pink and black pattern, hence its name. It will slightly jitter at all times, as well as emitting a cloud of
particles.
¶ Behaviour
Notexture will spawn on the surface and start wandering around. If the player is within 50 blocks of it when it spawns, their screen will go black for half a second. It disappears during the day, and when present, it also prevents the player from sleeping via err.texture.
Every second, a Disruption block will spawn in a random location within 3 blocks of Notexture, including replacing existing blocks.
If Notexture spots the player, it will chase them at a speed slower than walking speed. If the player comes within 10 blocks of it, Notexture will disappear in a cloud of
null particles and one of the following will happen with equal probability:
