As their names imply, they are lights shaped to resemble spiders. They are always round on the edges of ledges. They are portrayed as stage background visuals for Hang Castle and they exhibit the same behavior as the skull lights seen in Mystic Mansion.
Light Spider Marks have no effect on the gameplay. However, they always refer to an invisible path, moving platforms, trail of Rings or anything of importance that the player must notice.
