Shuriken Flowers are a type of Power-Up that Mario uses. When Mario collects one, he turns into Shuriken Mario. He can then throw shurikens at enemies like Shuriken Bros. The shurikens can hit up to 3 enemies at a time (similar to the Bloomerang plant from Plants vs Zombies 2) and when you spin while throwing shurikens, then they will go in all directions. They first appeared in Super Mario 3-D Galaxy.
