Madame Jujube is an exorcist[1].
Riff and Torg hire her to perform an exorcism after Angela is possessed by Beth. When the seance angers Brie Meighsaton, who begins flinging furniture around, Madame Jujube steals Torg's wallet and runs away.
They later hire her again to explain why Torg can see the ghosts trapped in Brie Meighsaton house but Zoë can't. This time, Madame Jujube steals all of their silverware, unaware that it's actually plastic cutlery painted silver (Aylee having eaten all the real silverware)[2].
