What was the name of the fairy in the British TV cartoon series "Willo the Wisp"?

"Willo the Wisp" is a British TV cartoon series originally produced in 1981 by the BBC and narrated by Kenneth Williams. It became popular with children and adults as it bridged the gap between the end of weekday children's programming and the early evening news.

The series was written and directed by Nick Spargo and produced by Nicholas Cartoon Films in association with the BBC and Tellytales Enterprises. The character of "Willo the Wisp" originated in an educational animation created by Spargo for British Gas plc in 1975 and the stories were set in Doyley Woods, a small beech wood in Oxfordshire, near the director's home.

Kenneth Williams provided voices for all of the characters. The principal narrator, Willo the Wisp, was a blue, floating creature drawn as a caricature of him, while the name refers to the ghostly light will-o'-the-wisp from folklore. The other main characters were Arthur the caterpillar (as a gruff cockney), Mavis Cruet, a plump, clumsy fairy with an erratic, magic wand, and the principal antagonist, Evil Edna, a witch in the form of a walking, talking television set who could zap people with her aerials.
