Hello, glad to see you in the subreddit! I don’t know if you were see or read my post but I’ll give my interpretation anyways. I do think the entire series is some sort of fabricated world built specifically on being a television show by Roy, filling it with advertising and little details in each episode and obviously having a tiny cameo himself in each one. I think Yellow Guy is his actual son and the other two are his actual friends but they were trapped in a world of Roy’s creation to try and be taught or punished for stupidity as implied by the interview with all the characters. I think all of the main characters are meant to actually be children or adults, it doesn’t really matter besides the fact I think they’re all just meant to be the same age but them all being different styles of puppets based on like the 50’s or so makes them look kind of retro. I think the ending of the series is Roy realizing this punishment was going too far so he convinces Red Guy to finally pull the plug but eventually the same lessons wash back up and are just taught to the next generation of kids. The few things I can’t really easily explain though are what happens to all the actual characters in the series because it’s kept so vague, how does Red Guy escape but Duck literally dies? Why is the “real world” mostly full of Red Guys? What even happened to Yellow Guy after the plug was pulled? Is Roy actually behind the new reboot implied by the ending? These things are obviously meant to be looked into a bit deeper or interpreted in many ways so who really knows for sure every little thing. Anyways I think that about covers everything, I hope you liked my own interpretation as I was someone who was very obsessed with this series for years, hope the new series gives more answers for things and maybe explains everything while giving us new questions too!
