A group of Muppets with Jim Henson in the middle.
The Muppets are a group of puppet characters known for an absurdist, burlesque and self-referential style of variety-sketch comedy. Created in 1955 by Jim Henson, they are the namesake for the Disney media franchise that encompasses films, television series, music recordings, print publications, and other media associated with The Muppet Show characters.
The Muppets were the stars of multiple television series and films, including; The Muppet Show (1976–1981), The Muppet Movie (1979), The Great Muppet Caper (1981) and The Muppets Take Manhattan (1984). After Henson's death in 1990, The Muppets continued their presence in television and cinema with Muppets Tonight (1996–1998), a series continuation of The Muppet Show, and three films, The Muppet Christmas Carol (1992), Muppet Treasure Island (1996), Muppets From Space (1999), the former two were co-produced with Disney, who sought to acquire the characters since the late 1980s. In 2004, The Walt Disney Company purchased the rights to The Muppets, and later formed The Muppets Studio, a division created specifically for managing The Muppets franchise.
Disney underwent an extensive re-branding of the franchise beginning in 2008, in anticipation of the seventh film; The Muppets. The film, written by Jason Segel and Nicholas Stoller and directed by James Bobin, was released by Walt Disney Pictures on November 23, 2011, and met with critical acclaim and commercial success. The eighth film, Muppets Most Wanted, was released in 2014.

Fozzie Bear (which is a common design for a Muppet)-
is a character with a very wide mouth and large protruding eyes.
The puppets are often molded or carved out of various types of foam, and then covered with fleece, fur, or other felt-like material. Muppets may represent humans, anthropomorphic animals, realistic animals, robots, anthropomorphic objects, extraterrestrial creatures, mythical beings or other unidentified, newly imagined creatures, monsters, or abstract characters.
Muppets are distinguished from ventriloquist "dummies"/"puppets", which are typically animated only in the head and face, in that their arms or other features are also mobile and expressive. Muppets are typically made of softer materials. They are also presented as being independent of the puppeteer, who is usually not visible—hidden behind a set or outside of the camera frame. Using the camera frame as the "stage" was an innovation of the Muppets. Previously on television, there would typically be a stage hiding the performers, as if in a live presentation. Sometimes they are seen full-bodied. This is done by using invisible strings to move the characters' bodies and mouths, and then adding the voices later.
Muppets tend to develop, as writer Michael Davis put it, "organically", meaning that the puppeteers take time, often up to a year, slowly developing their characters and voices. Muppets are also, as Davis said, "test-driven, passed around from one Henson troupe member to another in the hope of finding the perfect human-Muppet match".
When interacting with Muppets, children tended to act as though the Muppets were living creatures, even when they could see the puppeteers.

Kermit the Frog, arguably Jim Henson's most famous Muppet creation, was the star and host of The Muppet Show, played a significant role on Sesame Street, and served as the logo of The Jim Henson Company. He continues to star in the Muppet movies and makes numerous TV appearances.
Kermit grew up with thousands of siblings and has talked occasionally about other members of his family. His childhood adventures were chronicled in the 2002 direct-to-video film Kermit's Swamp Years. Kermit also has a nephew named Robin.

Miss Piggy insists that she and Kermit were married in The Muppets Take Manhattan, and that they're very happy. Kermit disagrees, claiming that it was just a movie and that in real life, they have a "professional relationship" (meaning he thinks they're professionals and she thinks they're in a relationship).
Kermit's most well-known catchphrase is "Hi-ho, Kermit the Frog here!" He typically introduced acts on The Muppet Show by waving his arms wildly and shouting "Yaaaay!" (a technique he learned from his old acting coach, Mr. Dawson).
Kermit has been credited as the writer of three books: For Every Child, A Better World; One Frog Can Make a Difference; and Before You Leap.

Kermit has made the jump from television and movies to Internet popular culture via the meme. While Kermit's meme popularity has waxed and waned, he has been a popular source of memes, especially the "But That's None of My Business" series since 2014. Other popular Kermit memes include Evil Kermit as well as Scooter Kermit.
"But That's None of My Business" memes feature Kermit drink a glass of tea or less frequently a glass of milk, sarcastically minding his own business while commenting on the foibles of others.
Kermit has some apparent siblings shown on the wall just northwest of the Cache location here. It was some interesting artwork found while wandering the neighborhood.
