Cornstalker

Appearance
Cornstalkers look very similar to the corn in the maze but have glowing blue eyes.

Behavior
Cornstalkers will occasionally appear behind the player while they are walking. They act as a wall that the player cannot go through, but that other antagonists can. They can be defeated with three hits from the axe.

Strategy
Cornstalkers are not usually an immediate hinderance, but they may get in the player's way later if they go back down the same path. If the player is not in any immediate danger it is wise to eliminate Cornstalkers as soon as they spawn.

Trivia

 * Prior to the 2.2 update, Cornstalkers looked identical to the maze corn.
