At some locations, messages will periodically appear on screen that serve as warning that a certain type of enemy will likely appear.
Note that the warning can refer to either a stationary enemy that spawned with the creation of the area or one that has a chance of spawning while the player is there. There is generally no correlation between the time the message appears and the delay before an enemy appears.
