The Crimson Mimic is a miniboss that spawns rarely in the Underground Crimson. They can also be spawned by putting a Key of Night into any empty chest. The chest will then turn into a Crimson Mimic in a hardmode world that contains the Crimson. They can be detected by the Lifeform Analyzer or any of its upgrades. Like the Corrupt Mimic and the Hallowed Mimic, they do not resemble any actual chests that can be used by the player, therefore they are easier to identify.
