The transformation scene is a theatrical convention of metamorphosis, in which a character, group of characters, stage properties or scenery undergo visible change. Transformation scenes were already standard in the European theatrical tradition with the masques of the 17th century. They may rely on both stage machinery and lighting effects for their dramatic impact.

Pantomime is a type of musical comedy stage production designed for family entertainment. It was developed in England and is performed throughout the United Kingdom, Ireland and in other English-speaking countries, especially during the Christmas and New Year season. Modern pantomime includes songs, gags, slapstick comedy and dancing. It generally combines gender-crossing actors and topical humour with a story more or less based on a well-known fairy tale, fable or folk tale. Pantomime is a participatory form of theatre, in which the audience is encouraged and expected to sing along with certain parts of the music and shout out phrases to the performers.
