He was called to Shelter 17 by Leonard McLeish, who had become convinced the dogs at the shelter were secretly aliens. The Pound Puppies removed any evidence that would point to their operations before Sculder arrived, making McLeish seem delusional. Dr. Sculder denounced McLeish for wasting his time, telling his viewers not to listen to crazy alien theorists like McLeish, but to reliable alien theorists like himself.
- Physically, Dr. Sculder resembles Dr. Emmett "Doc" Brown from the Back to the Future franchise. However, his name is a portmanteau of Agents Mulder and Scully from The X-Files.
