Hoborg's first true son. He was created to have a happy and simple life in the Neverhood, together with his father and some brothers who yet had to be created.
But Klogg decided that he'd rather want to have this world for himself. He took the throne and destroyed Hoborg's dreams and long-year work to follow his very own plans. Soon the Neverhood was inhabitated by evil beings and nasty creatures.
The only one who was left after that was Willie Trombone, who had to watch helplessly as even his Big Robot pal Bil was turned to 'bad'. For a long time all he could do was trying to live in this lonely world. Someday, though, when Klogg wasn't watching, he found a lifeseed that Hoborg had planned to be his next son..
