Asides from the vastly-known Thistlean Phenomenon, many other strange and/or unorthodox forces and even entities have been found either influencing PixelThistle media, or exclusively found IN PixelThistle media, when they aren't supposed to be.
These occurences are known as Pixanomalies. This page serves to document a list of all currently known Pixanomalies, as well as their containment status. (If they can be contained at all.)

Entities

Sentient and/or living entities that have been found within or are related to PixelThistle media.

Lye

Status: Pending.

Lye is a strange entity found within a supposedly unreleased update for the original A Week at Eli's.
Said update, Version 1.1b, was found in the unshared projects of PixelThistle's old scratch account, PiggioWikiGuyAGain. They appear to resemble Eli's appearance within AWAE, yet there are so many vast constrasts between the two it's obvious it's not Eli.
The version of the game containing Lye is not currently in our possession, and very little of its contents have been documented.
If obtained by us, it is unlikely to be released to the public in order to prevent Lye from spreading beyond his copy.

Bit

Status: Unknown, presumably free.

Bit is a noticably smaller stylization of an older look of Pixel's. They seem to exist within some kind of white void.
We have yet to locate them, or even meet them ourselves yet. We have also confirmed a multitude of times with Pixel that he didn't create it.

Green Pixel

Status: Unknown

A sentient being that resides in Discord servers. Simply an older design of Pixel but with neon green fur.
Has only ever been encountered once, sometime in 2024, and hasn't been seen since, suggesting sightings are very rare.
Non-hostile, so we've allowed them to roam free since said single encounter. Still worth documenting, however.

Forces

Mysterious forces of unknown origin and intent that can be tied to a recurring Pixanomaly.

The Thistlean Phenomenon

Status: Uncontainable, Passive Force.

The Thistlean Phenomenon is the generalized term for when Pixel appears in a video game and exerts his influence upon it, commonly making various changes to said game to account for his presence. Some changes are small, others are large. Documentation of the phenomenon is internal property, however may soon be publicised to help the general public better understand this Pixanomaly.

Repeat instances of the Thistlean Phenomenon are possible, and quite frequent. When compared to previous recorded instances of the same game, runs are more often than not identical, if not slightly modified. This suggests that Pixel has these runs prepared prior to appearing in a copy, or saves runs from prior instances. It is most likely the latter, meaning Pixel is able to travel into the digital plane.

Scratch Cat Ending

Status: Uncontainable, at large.

The Scratch Cat Ending is a rare phenomenon that can occur while browsing any project by the PiggioWikiGuyAGain account.
It causes the entire project to stop and be replaced by a static image of Scratch Cat recolored to look like Eli in a white void, with golden text towards the bottom reading "YOU GOT: THE SCRATCH CAT ENDING".
It is unknown where this image originates from, what force causes it, or if it has malicious intent or not, but for now it is merely a mild annoyanace, and can be removed by refreshing the page.

Misfits

Pixanomalies that don't fall into the previous two categories, but still have a clear connection to PixelThistle media.

Miscellaneous

Pixanomalies that are so loosely tied to PixelThistle, they could be mistaken as something else entirely.

Experiment #1187

Status: Hostile, at large.
