Molly recorded Rebound singing on her cellphone's camera, and her brother ended up posting the video on the Internet. The video quickly went viral. McLeish attempted to exploit Rebound for fame by making his own singing dog movie. The Pound Puppies then had to discredit the video so no one would find out that dogs can talk. By the end of the episode, the Pound Puppies succeeded in making the humans believe that the video was fake. Molly assumed that what she witnessed Rebound doing was a hoax, and she ended up adopting Roxie, a Dalmatian puppy.
Molly has blonde hair (in pigtails). Molly wears glasses, a violet beret (with matching scarf) and a uniform.
