Dottie McStuffins, better known as Doc McStuffins or just the Doc, is a cute and sweet 6-year-old girl who is the main character from the Disney Junior series Doc McStuffins, as well as a recurring character from the Rocko franchise series Barney and the Rocko Squad. In her original show, she loves to talk to toys and mend them. They come to life with the magic from her stethoscope. She cares for her friends and patients, including Lambie. She and Lambie are best friends are are always there for each other. Whenever a toy needs help, Doc always thinks carefully before she figures out what the problem is. In her Rocko franchise show, she is Orbit's close friend and also a friend to Alisa Bosconovitch. She always falls asleep, and snores as well to infuriate Evil-Man.

Kiara Muhammad is the Doc's voice actress in both Doc McStuffins and Barney and the Rocko Squad.
