Sillywhim is one of the three protagonists of Wee Sing in Sillyville. She is a free-spirited woman who used her magic to bring Scott, Laurie, and their dog Barney to Sillyville. She possesses a sparkling bubble-blower-like object shaped like a musical note that shoots rainbows. These can make people appear or disappear, transport objects, people from place to place, and push people backward. In Wee Sing in Sillyville, when the people didn't get along, her outfit lost its color and it became all white. When they got along again, her colors returned.
She is played by Renee Margolin. Renee currently works at her family's business in Houston, TX.
