Dennis's Granny, voiced by Sally Grace. Although she is eighty years old, Dennis's Granny is still very young at heart. Dennis loves his Granny, he defends her when another speaks ill of her ("Dennis and the Beanstalk"), and will come to her for advice in times of need ("The Day TV was Banned"). In her youth, Dennis's Granny was every bit the Menace towards anything like a peaceful society in Beanotown that her grandson is today, as revealed in "The Secret Diary", and in her day there was a police officer, Sgt. Boot, who was the "Sgt. Slipper" to her "Dennis".
