I always found it interesting that some of the Muppets had real animals for pets, like Telly had a real hamster named Chuckie Sue, Elmo had a real goldfish named Dorothy, Ernie brought home a real puppy that he and Bert couldn't agree on a name for . . . then Baby Bear had a Muppet parrot for a pet named Ralphie (or "Walphie" as he said, lol).
