According to writer Paul Dini, he and storyboard artist Warren Greenwood were big fans of Matt Groening's "Life In Hell" comic strip and the original idea for the Plundor character was to base him on Groening's Binky the Rabbit.
The Script was loosely based on the premise "He-Man Who?" in which Desira (later renamed Evil-Lyn) wipes He-Man's mind, and only Man-At-Arms can restore his memory. Paul Dini's version was approved May 10, 1983 and final script revision dated May 13, 1983.
Paul Dini's script revealed that Gleedil's pet was known as a 'Tiger-Wolf', while Plundor's droids are referred to as 'Rabbots'. He also specified that the Shminvats should speak like the Jawas from Star Wars: Episode IV - A New Hope (1977) and described Plundor as a fearsome looking, armor-clad villain with ears that, in silhouette, resemble horns.
The rainbow effect and backgrounds seen while characters travel through the Crossroads to All Universes would be re-used in The Return of Granamyr (1983), Into the Dark Dimension (1985) and The Greatest Magic (1985).
