What is "grotbags"

Grotbags is a television series about a fictional witch called Grotbags, who was a popular fixture on British children's television during the 1980s and early 1990s. A character sculpted very much in the mould of the traditional pantomime villain, Grotbags has always been played by actress and singer Carol Lee Scott in a costume comprising distinctive vivid green make-up and a witch's cape and hat.
