Mrs. Grouse

Mrs. Grouse is a babysitter of Arthur and D.W. who Arthur disliked because she made him and D.W. dance, which he hated. D.W. liked Mrs. Grouse, saying that she smelled nice. At the beginning of the episode Mrs. Grouse couldn't watch D.W. and Arthur so they got a new babysitter Sally McGill who Arthur really liked because she was into video games. Later on when Arthur talks his parents into going out again he hopes that the babysitter is Sally so they can play a videogame but to his horror it's Mrs. Grouse who makes Arthur and D.W. dance..
