South Park Archives

The DOI Agents are representatives of the United States Department of Interior who appear in Season Three episode "Jakovasaurs".


Upon discovery of a female Jakovasaur, it was taken to the City Hall and presented to three Department of Interior agents. The agents claimed that a live Jakovasaur had never been seen, and requested that it gets a chance at repopulation, granting a Jakovasaur couple to a new home where it can produce offspring.

Upon realizing that the Jakovasaur population had grown out of control, the agents decided to flee South Park, but not before appointing Eric Cartman an official member of the DOI, granting him authority over all wildlife in South Park.


Each of the agents wear working suits of different colors, and a pair of black square-framed glasses.
