This is the new type of "Female" skull that Bungie has placed in Halo 3. This one is called the "Tidy Up Skull" refering to how women always want everything clean. When you put this skull on you must go through the whole level without leaving any nades or weapons behind. If you find any nades or weapons you must dispose of them before you get another checkpoint. This skull along with others (listed below) are hints of what Halo 3:Recon will be like. - Kiss you Goodnight - Do your homework! - Go Hilary Clinton!! - That time of the month. These new skulls give you an acheivement that gives you new armor. They give you new armor that really show a female spartans "curves".
