Reginald was a homeless man the CIA tricked into participating in one of their mind-swapping experiments, swapping his brain with that of a koala much like Klaus was switched to a goldfish. Reginald now works for the CIA, relying on his cuteness to infiltrate various agencies. Like Klaus, he also has a bit of a libidinous streak.
In "Bully for Steve", Reginald and Hayley go to a carnival where she sees her ex Jeff, then later tells Reginald that she still has feelings for him. He explains that he loves her, and always has. He sings to her then makes fireworks noises and hand motions.
In "100 A.D." Deputy Director Bullock uses Reggie as his personal chauffeur.

When Bullock continues to talk dirty about Hayley, Reggie takes his cellphone to call Bullock's mother.
In "Gorillas in the Mist", Reggie invites Stan, Dick and Jackson on his houseboat to look for women on passing boats. When Stan is forced to bring Steve along, he wins over the guys by telling a dirty joke although Reggie's boat crashes and sinks another boat and Reggie is eventually arrested.
In "Family Affair" and "Wife Insurance" Reginald was voiced by Donald Fullilove, who is best known as Goldie Wilson from Back to the Future. Show writer Erik Durbin took over the role beginning with "The Return of the Bling".
