Unbeknownst to the Ducks, however, a civilization of slimey Shape-Shifter resided in an underground world below the Island. Having observed the surface-worlders, one of them decided to impersonate Launchpad McQuack and go back to Duckburg, while Launchpad was convinced to take a holiday in the Shape-Shifters' underground world, playing video games with them.
