The Royal Flail is a key item that appears in Wario: Master of Disguise.
The Royal Flail is a small flail that is light blue and yellow in color.
The Royal Flail is an important item that can be found in Poobah the Pharaoh's Pyramid. In order to access it, Wario must transverse through dark rooms until he reaches one with two Scare-Ohs! in it. After defeating the Scare-Ohs!, the purple chest containing the Royal Flail will appear. The Royal Flail can then be used on a mural that unlocks a door allowing Wario to proceed.
