Knuckles appears in the Here's Hamton episode segment, America's Least Wanted as the main antagonist. Plucky has invited himself over to Hamton's house, and while he is channel flipping, he watches America's Top 10 Criminals, where he finds out Knuckles is currently public enemy #1, and that he is most likely living nearby under an assumed name. Due to Knuckles' resemblance to Hamton, Plucky is worried he might have been best friends with a master criminal.
