From the latest issue of Entertainment Weekly, here's the first-released photo of the main, largely-puppet-based cast of the latest Muppet movie. Assuming you've seen at least episode of both The Muppet Show and How I Met Your Mother, you should recognize everyone here except for the guy holding up the modern technology reference. He's a new character, Walter, who the weekly entertainment periodical described as:
"a sweet, slightly naive twenty-something Everypuppet who, in the movie, is the best friend and roommate of Segel's character, Gary. Both Gary and Walter are die-hard Muppet fans."
We'll have to take their word it isn't just a foam-covered Chris Kattan.
