The Fortnite x Teenage Mutant Ninja Turtles event is now live; gamers can enjoy this crossover until February 27 at 9 AM ET. During this event, gamers must earn as much Ooze as possible so that they can fully complete the Cowabunga event pass and unlock all rewards. Even though most of the rewards are unlockable as gamers get more Ooze, there is another currency that they must earn in order to get a special item: the Krang back bling.
