Thunderclutch Whirlydingy
From Multiversal Omnipedia
The Thunderclutch Whirlydingy was a sports car capable of transforming into either a helicopter or a speedboat by pushing the appropriate buttons on a special remote control. It was invented by Gyro Gearloose during his time as the DIA's Dr. G, and presented to McQuack, Launchpad. He crashed the first vehicle before even he even left DIA headquarters, but luckily Gyro had a spare.
