Fughetta Faffner

From Muppet Wiki

Fughetta Faffner is the star of The Ghost of Faffner Hall. She loves everything about music, and has turned her ancestral home, Faffner Hall, into a music conservatory.

Being a ghost, she is normally transparent, but whenever she hears good music, she slowly solidifies. In addition to becoming invisible, she also has the ability to temporarily stop time in order to fix things in the present.

She has had the pleasure of working with the best musicians and composers, both living and dead. She's taken singing lessons from Marion Montgomery, and dined with Puccini and Rossini.

Fughetta regularly converses with the busts of three famous composers -- Ludwig van Beethoven, Wolfgang Amadeus Mozart and George Frideric Handel.
