Sylphia Flapper

Miss Sylphia Flapper is the temporarily new teacher at Monster High in the book, Ghoulfriends Forever, which is part of the Ghoulfriends series.

Personality
It is heavily hinted that Miss Flapper must be cunning and/or evil, because she apparently has the power to hypnotize monsters, and she does so in the story, almost convincing all of them to go on a war against the normies, only for her plan to be ruined by Robecca, Rochelle, Venus and Cy.

Physical Description
Nothing much is described about Miss Flapper, although it is constantly mentioned throughout the book that she is quite attractive.

Family
Aside from the fact of whatever family she may have are dragons, nothing is known of Sylphia's family.

Friends
Miss Flapper does not have any friends, so to speak, except for a group of trolls that happen to be her slaves.
