Kicking off the World of Warcraft fifth anniversary celebrations is a new World of Warcraft commercial featuring Mr. T which advertises a new item now available to North American players called "Mohawk Grenades". When thrown, these "Mohawk Grenades" will turn other players into "Night Elf Mohawks" giving them a temporary "t-rrific" new haircut.
Players can acquire the Mohawk Grenades by visiting Night Elf Mohawk NPC's camped outside of every race's starting zone. The grenades have five charges and can be re-acquired to your hearts content.
European and Korean players will be able to join in on the fun starting November 24th, 2009. For more details, read the "Mohawk Grenade" FAQ
