Dog (King Charles Spaniel and Beagle mix)
Episode 1 "A Ruff Start" (Dogcraft)
Molly's original name was Diva at the time of the adoption, however, Stacy decided to change her name to Molly. Stacy soon realized that Molly's previous name was very fitting to her personality, and occasionally calls her Diva.
Molly was rescued on August 12th, 2011. Stacy already had both Page and Polly before Molly, however she needed to move for work, and had to leave Polly. This is what made Stacy decide to rescue another dog.
Stacy originally saw a picture of Molly, who was at the time named Diva, on a web page on Petfinder.com, which struck Stacy's interest. She asked about the dog, learning that Molly was very neglected and was extremely emaciated, only weighing 10 pounds, and worst of all, also had Heart Worm, a very potentially deadly disease that is transmitted by a mosquito. Molly's foster owners were unable to get Molly the treatment she needed for Heart Worm, a very expensive treatment, so Stacy volunteered to adopt the dog.
After passing the adoption home study process, Stacy was finally able to meet and adopt Molly.
Soon after adopting Molly, Stacy took her to the vet where she learned that Molly not only had Heart Worm, but she had a lot more of diseases, like Hook Worm, an ear infection, and dry skin. Stacy then took Molly to a specialist heart vet, where Molly was X-rayed.
The vet said that they had to start a treatment, but also warned that the medicine would kill most of the worms, which could also kill Molly by having dead worms floating in her system.
While Molly was having her medicine, Stacy had to move to Los Angeles, and Molly’s treatment lasted several months. Afterwards, Stacy had to get Molly to a cardiology vet, which costed almost three thousand dollars in total. Luckily, Molly fully recovered, and Stacy considers Molly's previous name, Diva, very fitting due to how expensive the dog was to take care of. 
Molly is considered a 'Diva' by Stacy, in "Molly's message to her fans" Molly is seen as very lazy and doesn't see the point of Minecraft. She loves attention and to be played with but doesn't enjoy going out for walks.
Stacy has also mentioned how Molly frequently becomes sick and has shown the medicine Molly needed on one occasion. Molly is also mischievous, this is seen in her knocking things over and disorganising items.
In Dogcraft Edit
Stacy named a dog in Dogcraft after Molly, she first appeared in episode 1 and has since moved into Stacy's home. Molly in Dogcraft was notable for being the very first dog that Stacy tamed. However, instead of a red collar, she was given a white collar.
Molly was also featured in the 'Dogcam', which showed Page and Molly resting or playing and doing tricks. However, after a few episodes, Stacy decided to remove the 'Dogcam' from Dogcraft episodes.
In episode 137 of Dogcraft, Molly was taken to the Dog Wash 2000, and when she emerged she appeared with a different appearance, now looking more like her real-life self. In Dogcraft, she is in love with Wink.
