Party-Hearty Quadra Sonic Rock 'N' Roller

The Part-Hearty Quadra-Sonic Rock and Roller is a device created by Rotor Walrus in the year 3235. When spun in the hand, it goes from a power drill to a bazooka like weapon with gun barrels attached. Another spin and it will transform back into a drill. When Rotor showed it to Sonic, he was startled by the size and asked if it could blast though different zones. Rotor said it could, but only in extreme circumstances. (StH: #44)

Rotor later used it to destroy some wall turrets that were aiming at Sally during an attack on Robotropolis. He was pleased with his work until Antoine told him to focus on the mission. (StH: #47)

It's final use was when Robotnik invaded Knothole by orders of the fake King Max. Rotor fired the gun at him only for Robotnik to block it and fire his own bolt of energy at it saying that it was "quaint but ultimately inferior". (StH: #48
