The third season begins and now in Smell-O-Vision, DJ and Harsha track skunks and find out how to use chemistry to neutralize skunk spray while Jay and Sam learn to "brave the waves" and become junior lifeguards.
In the third season finale, Ruff's twin brother Scruff takes control of the show, renames it "FETCH! with Scruff and Ruff Ruffman", and designs a series of elimination games for the contestants.
This is Season 3 episode 2 "When a Home is a House of Cards". Ruff sends Jay and Noel to learn card-stacking, and Sam and Sammy to make a PSA for an animal shelter.
Noel, Sammy, and Jay are dispatched to Thompson Island where they learn about insects and their habitats while Harsha learns about pow wows in New Mexico.
The Fetch 3000 crashes, so Ruff calls Glen, but Glen will only fix it if he can do something on the show. Glen decides to send all the FETCHers, dressed as Elves, Dwarves, and Wizards, on a mythic Live Action Role Playing mission!
Ruff sends Sam to a high-level meeting with Senator Ted Kennedy. Meanwhile, Noel, Sammy, and DJ are challenged to design a float for Ruff's political campaign.
