Shuriken

The  is an Obstacle found in the Dojo Stage. It is thrown by training dummies at the player on the left side of the stage. If the collides with the player, it removes the limb that touched the, or kills the player if it collides with the head.

Trivia

 * The training dummies will always aim the Shuriken and Kunai at the player (decoy boats do not fool it). However, the weapons take time to reach the player and their boat. As the boat is constantly moving forward, the weapons always hit the boat late and thus, they very rarely hit the player.
