Shuriken

The Shuriken are a special item in Paper Mario: The Origami King. They are found in Shogun Studios, and given by a Ninji after Mario gives him the Straw. Due to Japanese grammar conventions which don't differentiate between singular and plural objects, the Shuriken might be mistaken for one shuriken, when it is actually several shuriken on a ring. It can be given to the owner of the Shuriken Dojo to open the place and allow Mario to play its minigame, earning the Baseball if he succeeds.
