Dr. Murkin

Dr. Murkin is a semi-antagonist in the twenty-sixth Goosebumps book My Hairiest Adventure and its accompanying television adaptation.

History
Dr. Murkin is introduced as the doctor for Larry Boyd, often administering shots for Larry due to his lack of sweat glands. He gives Larry shots every two weeks. Throughout the course of the story, Larry begins to grow hair at a rapid pace. A reaction he originally believes has to do with the expired bottle of Insta-Tan lotion he and his friends found and used. However, Larry's friends begin to disappear one by one until Larry deduces that they've all been turned to dogs. After his body becomes completely covered in hair, he rushes home where he's greeted by his parents and Dr. Murkin. Murkin reveals the truth to Larry. The town they live in is actually a government testing lab and the adults all work for Dr. Murkin. Years ago, Dr. Murkin found a way to turn dogs into humans, and experimented on several dogs, including Larry and his friends. It's why Larry actually needed the shots. However, the serum eventually fails and turns the humans back into dogs. Realizing the pain it causes the families who adopted the dog-humans, he gives up experimenting on dogs. However, after the Boyd family bring home a human baby named Jasper, it's assumed that he now experiments on cats instead.

Neither the book nor the episode explain exactly why Dr. Murkin created this experiment, yet the prevailing belief was that it was a way to help couples get around the adoption process.

Dr. Murkin is described as being a rather good-natured man who Larry likes, despite constantly giving him shots.
