What kind of beings are Nigel and Randy anyway? Are they Kirby’s daddies?
Nigel and Randy (as well as any armless floating ball that may appear on the strip) represent the conflicting consciousnesses of both reason and temptation; they literally are the metaphorical angel and devil that appear on your shoulder when you’re in a moral dilemma. They’re from heaven and hell, respectively, and have no hands or arms to symbolize their inability to physically interact with the living world. Since Kirby has arms, and Nigel and Randy clearly do not sport any reproductive organs, your second question is stupid.
