Ms. Grunion (real name: Edwina Grunion) is the main antagonist of DreamWorks's 28th full-length animated feature film, Mr. Peabody and Sherman. She is a plump, strict, and cat-loving school counselor.
She was voiced by Allison Janney who also played Gladys Sharp.
After Sherman bites his classmate Penny Peterson for calling him a "dog", Ms. Grunion is determined to have the adoption agency reclaim Sherman from Mr. Peabody permanently.
Later on, after she did try to take Sherman away, Mr. Peabody's fatherly instincts got the best of him and decided to do what Sherman did to Penny the day before; by biting her arm. Ms. Grunion called the police to have him arrested while a hole was ripped in the space-time continuum.
In the end, she got dragged back in time by King Agamemnon and the large duo were married, while she became a kinder and happier person.
Mrs. Grunion is a dastardly, scandalous, underhanded, manipulative, and untrustworthy, social worker who is attempting to get Sherman taken away from Mr. Peabody. However, she does not acutally care for Sherman's well being, she actually wants to ruin Sherman's and Mr. Peabody's lives and make them miserable. She even went to as far as reporting Peabody with a false accusation.
