The 星云浮怪 is a 困难模式, post-拜月教邪教徒 flying 敌怪 that spawns near the 星云柱 during the 月亮事件. It periodically spawns miniature eyes that float around it. Its main attack is either ramming into the player, or by distancing itself and proceeding to shoot a pink Nebula Laser from one of its followers at you, dealing significant amounts of damage. It will also try to teleport around the player while firing its laser, appearing to do this more often in 专家模式. It is one of the enemies of the Nebula Wave that must be paid attention to. They are somewhat common and in groups can overwhelm the player.
