King Goshposh was created for Jim Henson's failed 1962 pilot Tales of the Tinkerdee, and also appeared in another pilot, The Land of Tinkerdee. Goshposh was a genially dunderheaded monarch, with a fondness for parties and presents. He spoke with a broad Texan accent.

Goshposh finally appeared on screen in the 1967 summer replacement series Our Place (and on The Mike Douglas Show as "King Louie"), and took a leading role as Prince Arthur Charming's father in the 1970 special Hey, Cinderella! He later made an appearance in The Perry Como Winter Show in 1972, playing a hotel manager.

King Goshposh smoked a cigar in many of his scenes; unlike other Muppet cigar-chompers, his was actually lit. In his appearance on The Mike Douglas Show, conversing with Hermione Gingold, Goshposh explains that he has in fact lost his kingdom: "I blew it."

A refurbished, full-body version of the puppet, renamed King Rupert the Second, was featured in the 1971 special The Frog Prince and in The Muppet Show Episode 121.
