Donald Duck universe
Donald Duck and his maternal uncle Scrooge McDuck received nearly equal exposure in comics. Other primary characters include Donald's three young nephews Huey, Dewey, and Louie, and girlfriend Daisy Duck.
Silent Running
Enlisting the aid of the ship's three "drones" (service robots), Huey, Dewey and Louie (named after Donald Duck's nephews), Lowell stages a fake premature explosion as a ruse and sends the "Valley Forge" careening towards Saturn in an attempt to hijack the ship and flee with the last forest dome. He then reprograms the drones to perform surgery on his leg and sets the "Valley Forge" on a risky course through Saturn's rings. Later, as the ship endures the rough passage, Drone 3 (Louie) is lost, but the ship and its remaining dome emerge relatively undamaged on the other side of the rings.
