Ms. Grunion

"It's normal for children to tease. It's not normal for them to bite! Clearly it's because of how he's being raised. In my opinion, a dog can never be a suitable parent to a little boy."

- Ms. Grunion Ms. Grunion is the main antagonist of Mr. Peabody and Sherman. She is a plump, strict and cat-loving school counselor.

In Mr. Peabody and Sherman
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.
