Here's something else people may not know about... the Teletubbies we know today aren't anything like the Teletubbies that were originally conceived.
From what I've read from some kind of research years ago, Ragdoll/BBC, or whoever it was who produced the series, were originally wanting to create a children's sitcom, aimed at the 7, 8, 9-year-olds, about silly and bumbling astronauts/space explorers, and somehow, it underwent all these changes from various different people involved, to the point that it became a kiddie show, aimed at 1-2-3-year-olds, about these supposedly little kids who like to dress up as space explorers (hence their spacey outfits) and explorer their own fanciful little world they live in.
I confess when Teletubbies first came on PBS back in 1998, I DID watch it. I'm serious, I watched it... it's like what the Love Ducks did to Arthur... you really couldn't NOT watch it... all happy, and colorful, and hypnotic and everything... and I was 8 and 9 at the time, and my other classmates watched it too, again, it was that hypnotic factor of sorts, and apparently more older kids across the country watched like that as well... so that's the Krofft comparison, because their Saturday Morning shows were aimed at little kids, however, when stoned college kids got up on Saturday Morning, and saw these shows that looked like their acid fantasies, they started watching too... and again, none of this was ever intentional, that was just the style these shows happened to have. I remember even Jack Wild (who plays Jimmy on Pufnstuf) said he would get letters from people all the time saying things like, "Yeah man, I know how you feel, I talk to mushrooms too, and I never get any help from these guys."
