You'll need this special sonar cover, too.
Return of the Brigade is my idea for a sidequest in Fossil Fighters Champions. In it, the BareBones Brigade returns and they want to end the Super Cup. They then see you and decide to make you an official member. You are then given the 'BB Brigade Kit', a set of items from the Brigade. It has: A BB Brigade Mask, a B-Zino, a Don Boneyard Icon, and a B-Plesio (If you don't already have one). You then must register for the Super Cup.
