Mrs. Frazzle
From Muppet Wiki
Mrs. Frazzle is Frazzle's mother. She takes her son to the dentist and spends some time with him before his cleaning, to calm his nerves about the experience. When the dentist finally arrives, he addresses Mrs. Frazzle and sets his attention on Frazzle. At first gaze upon the monster's teeth, the dentist runs away screaming. Mrs. Frazzle deduces that the dentist was more afraid of Frazzle than Frazzle was of the dentist.
