|Spawns In:||Skull Cavern|
|Variations:||Bug, Armored Bug|
Flies back and forth in a single straight line between walls or objects. They are not aggressive, but will deal damage to the player on contact.
They cannot be killed (even by bomb explosions), but can be stopped by blocking it with a sword. Clearing obstacles in their flight path, such as stones, can give them more room to move which also gives the player more room to avoid them.
