Mantis Rock or Mantis Shrine is a monument area in Forbidden Valley. It is named partly after the Praying Mantises who call it home, and the Bell Shrine, which is located near the Dragonmaw Chasm Bouncer. Mantis Rock was the site of a great battle which took place long ago, and the Ninja erected many Ronin Statues to commemorate the fallen warriors. Unfortunately, Maelstrom energy led the Ronin to be assimilated into the Maelstrom. Although originally inanimate, the haunted armor became a deadly threat to the shrine.
