Killer Moths are enemies in Kung-Fu Master.
Killer Moths only appear through the first half of Floor 4. They appear from holes cut out from the wall. They hover in the air and fly through the hallway getting in the way. They can be punched or kicked, but their constant height change can make the challenging to hit. Generally speaking, moths that are behind you are safe to ignore unless you have to stop for some reason. Moths that appear in front of you should be attacked or avoided until they are behind you.
