The youngest children of the Otis family, the twins are wild hooligans. They throw pillows at the ghostly Sir Simon's head, hit him with their peashooters, and throw nuts along the corridor in an effort to trip the Ghost. Irrepressible, the twins achieve their greatest triumph when they create their own ghost from a hollowed-out turnip, a bed curtain, and a kitchen cleaver. Their constant pranks leave Sir Simon shaken, as his every plan for revenge is thwarted by the twins's efforts.
