Rainbow Enemy Phenomena

The Rainbow enemy phenomena is a rare occurrence that will make enemies completely invincible to the player and change their texture to a rainbow one.

Behavior
Rainbow enemies will be invincible to player’s no matter what they do and there is no reported way to kill them. The phenomena seems to be unable to affect enemies that use 2D textures like the Bob-omb and Pokey as there have been no documented cases of such an event occurring. Rainbow enemies have reported to move around the same and deal the same amount of damage on contact. It’s also been reported that anomalous enemies like Dry Bones and Shy Guys can also be affected by the phenomena, although it has been reported have glitchy textures and even crash the game.

Theorizing
Many people say that this is an instance of enemy discoloring although it effecting more than just one enemy has lead to many debates on whether or not it is an instance of enemy discoloration.

Some people theorize that these enemies are using Super stars (Not Power Stars) to make themselves invincible, henceforth why super stars never appear in the game and it could somewhat explain the texture.
