The Silly Sorceress is a magical monster who appeared in a season 29 episode of Sesame Street. She loves the letter S, to the point where she has it embroidered on her cap and cloak, possessing an S-shaped wand and speaking almost entirely in words beginning with S. She appears on Sesame Street unseen by anyone and introduces a silly spell she plans on casting on a nearby letter S: anyone who touches it will be stuck to it. Rosita happens to be the one to do so, ending up with it stuck to her nose.
