Well, I've noticed the Muppet folk bringing in bits and pieces of Muppet Babies over the years. MFS didn't introduce Gonzo as an alien. This was a major theme of Baby Gonzo. Super Gonzo is just one variation of the theme. Look how many times his imaginary worlds tend to be in space or on different planets. He also seems to be the one most associated with the magical closet gag, where it opens up onto different worlds (via clips). Letters to Santa gets Scooter his computer back. The comics are using lots of stories done on Muppet Babies. Animal befriended a bunny and has become a more sensitive ADHD fanatic, LOL.
I've always kinda considered TMM and MTM to be at least a highly similar universe if not the latter being a sequel to the other, with the Muppets originally going to Hollywood to make it big, but then end up in NY and decide to go to college and try Theater. GMC is obviously more like a movie-long sketch ... a stand-alone story. While I still feel that they are not "the truth" (since Kermit outright admits TMM is only sorta kinda true), I imagine it, like you said, has some elements vital to the characterization. It's not just Muppet Babies that messes with your head. Kermit's from the swamp (apparently near Disney World), I don't know enough about Sam & Friends to comment, but he has a house around Sesame Street that seems like a comfortable middle-class house, so where does Hollywood come into it? Actually, despite TMM, most of the action takes place in NY. It's more like TMM is the story of making that particular movie, not an actual origin tale. I'm not arguing that Muppet Babies is canon, only that elements from it are just as reasonable as other elements. You can be with other kids as a toddler and not really care about those people in your thirties. If I saw old classmates from elementary school ... I'd have to be reminded who they are. If there were long periods of time apart ... and, we're assuming everyone just forgot. It's also possible that they just don't bring up their childhoods (let's face it ... when you're roughly ageless, why bring up signs you age?).
You bring up a lot of good and intriguing points!
Did the Animal/bunny thing begin on Muppet Babies? Because most of the Animal sketches on Muppets.com involve the dynamic between him and "Bunny". I never really realized the space connection with Gonzo before, or the door portal connection on MB. Nice work! Remember how in The Dark Knight film, the Joker keeps changing his origin story...yet it seems to be a take on the 1988 graphic novel "Batman: The Killing Joke"? I bring that up as it seems sometimes in classic storytelling, there is multiple origin stories...but each one may have shades of truth to it.
Youre right, MTM seems very related to TMM. They already now know eachother, are in college but go to the big apple. I saw both in theaters and just assumed that TMTM was a sequel.
Now you're getting into an interesting subject of Muppet topology. WHERE are all these places located? I've often wondered that. If Kermit's home swamp is right near Walt Disney World, we can at least pinpoint where in Florida its suppose to be. But where is Fozzie's mom's place? We can assume it's relatively close to a big mall, since Piggy gets driven there from a department store.
Where is the KMUP studio, Muppet Central studio(Muppet Television from JHH) or the classic Muppet Theater? We've been shown Kermit's "apartment" in even modern Sesame episodes(an episode of Elmo's world), however I tend to look at this as a set piece set in the Sesame set world.
I agree with the toddler thing. We know of some of the Muppets parents, like Fozzie and Animal(at least from Animal calling his mom to announce the Webby's) What confused me is the scene in TMTM where Piggy imagines a what-if scenario, yet in MFC its assumed they made films together(tho, that was edited out for all official releases thereafter...so maybe its not canon?)
And then comes the issue of Fraggle Rock and Fraggle holes. We can assume there is one in Arizona where Doc moves to, as well as under Fozzie's mom's house. But given Uncle Matt was on a 1993 episode of The Today Show with Cotterpin Doozer, as well as Sprocket seen in the 1996 film Treasure Island...and given Red's appearance at Comic Con, it seems like the Fraggle Rock continuum goes on beyond the cancellation of the show. I imagine that the land of Fraggle Rock is relatively close to the land of "Ovadare"(where Scary Scary Monsters live)

It does seem like the spiritual birthplace and home of the Muppets has always felt like New York City, especially in the 1970's and 1980's. I imagine a scenario of where the Muppets simply were looking for work and all ended up together. Kermit and Rowlf of course being the original dynamic, pre Kermit-Fozzie. Rowlf to me is one of the most intriguing of Muppet characters...he reminds me of say, an old blues musician who knows a lot and been around a long time...but struggles to find work(as was referenced in the recent Muppets Kitchen episode)
