Wandering Eye Fish

The Wandering Eye Fish is a pre-Hardmode enemy that can be spawned by fishing in a Blood Moon. When the bobber dips and the player attempts to reel in a fish, a Wandering Eye Fish or a Zombie Merman has a chance to spawn within a few blocks of the bobber in place of a fish.

Tips

 * The Wandering Eye Fish has high health and defense, moves very quickly, and doesn't take knockback, making it a challenging enemy for underpowered characters.
 * One way to effectively fight the Wandering Eye Fish is to obtain a movement accessory such as a Cloud in a Bottle or Rocket Boots and make tight circles around the eye. Its top speed can easily outrun early-game players, but its turning radius is limited.
 * The Wandering Eye Fish cannot open doors, although all zombies during a Blood Moon can. Summons can kill it from a safe distance while the player hides inside a house.
 * Unlike most flying enemies, the Wandering Eye Fish can enter water, though it will still be slowed down when submerged.
 * If the Wandering Eye Fish is affected by the confused debuff caused by the Brain of Confusion, it may fly away far enough to despawn unless the player chases it.
