However, there isn't really a set "Five Famous Muppets" that were always featured. It depends on which era of The Muppet Show you're thinking of and what "famous" means to you.
Here are some of the most popular Muppets that were featured prominently in the show:
* Kermit the Frog: The leader and host of The Muppet Show.
* Miss Piggy: The demanding diva, who often falls for Kermit.
* Fozzie Bear: The lovable but terrible comedian.
* Gonzo: The eccentric and adventurous Muppet.
* Scooter: The overworked stage manager.
* Animal: The wild and crazy drummer.
* Bunsen Honeydew and Beaker: The mad scientist and his long-suffering assistant.
There were also other Muppets that appeared frequently, including Sam the Eagle, Dr. Bunsen Honeydew, Beaker, and the Swedish Chef. Ultimately, it's up to you to decide which five you consider the most famous from The Muppet Show!
