Found Aliens - The Galactic Pool Aliens Trilogy, #3

The Galactic Pool's greatest evil genius (or so he thinks) has arrived in person to dominate Earth. The local Higher Power fails to recognize the threat in time, so He's forced to recruit some familiar aliens to help keep Earth screwed over the way He wants it to be screwed over. As part of the deal, Jimmy Fresneaux obtains permission to abduct hundreds of Earthling bass fishermen for a pan-galactic bass fishing tournament.
And Trukk-9, the Galactic Pool's greatest filmmaker (or so he thinks), rides along to finish a destined-to-become-historic film about his favorite rogue Dnooblian. *There's only one sex scene, but it's a doozy. Too bad we get kicked out of the room.
