Yep, back in a Season 2 episode, "D.W.'s Deer Friend."
For context, they Reads went camping at D.W.'s insistance, and she wanted to meet wild animals, but her first encounter was such was a fish that Arthur and Mr. Read had caught and were going to eat for dinner . . . instead, they held a funeral for it because D.W. was upset over it being killed.
CBS reporter: So if Jim really understood the characters, you have been pretty critical of Disney for not sorta getting these characters.
Frank Oz: Not critical, it's weird. The trouble with print is they can't print tone, and my tone wasn't combative, my tone is hopeful and pleating. Because Disney really wants to do a good job, they're really doing the very best they can. The thing is what they don't understand is someone new can't just write for the Muppets. There are performers who have been with them for decades, and they're not being part of the process. Those people, Bill Barretta, Dave Goelz, they are brilliant, they know the soul, and I just wish they would be asked to be part of the creation, and that's what would make a success for Disney, really. So I have nothing against Disney, Jim wanted to go to Disney, absolutely.
