Since her debut in 1976, Miss Piggy is notable for her volatile diva personality, tendency to use French phrases in her speech and practice of karate. She was also known for her on-again/off-again relationship with Kermit the Frog, which began in 1978 and has been on a hiatus since 2015. Frank Oz performed the character from 1976 to 2000 and was succeeded by Eric Jacobson in 2001.
Rowlf the Dog Rowlf the Dog is a Muppet character, a scruffy brown dog of indeterminate breed, though part Corgi, with a rounded black nose and long floppy ears. He was created and originally performed by Jim Henson. Rowlf is the Muppet Theatre's resident pianist, as well as one of the show's main cast members. Calm and wisecracking, his humor is characterized as deadpan and as such, is one of few Muppets who is rarely flustered by the show's prevalent mayhem. He is very easy going and a fan of classical music (particularly Beethoven) and musicals.
