Ken first appeared in "Harvest Festival", where he asked Leslie Knope to relocate the Harvest Festival because it was taking place on the sacred burial grounds of the Battle of Indian Hill, where his ancestors were killed in a seven-day battle. When Leslie insisted there was nowhere she could move the festival without being offensive due to Pawnee's extremely bloody history, Ken threatened to place a curse on the festival. He believed his trick would frighten people enough to ruin the festival, insisting, "There are two things I know about white people: they love Rachael Ray, and they are terrified of curses." Ken's efforts proved successful, as the local media learned about the curse and reported on it so extensively that the festival was nearly ruined. After the TV crews overload the generator and shut off the power at the festival, Leslie goes to Ken at the Wamapoke Casino to ask him to borrow a generator. Leslie and Ken came to a compromise after Leslie agrees to place a Wamapoke history exhibit by the entrance of the festival. Ken lifts the fake curse during a phony ceremony, where he shouts nonsense chants, fooling the naive locals into believing the nonexistent curse has been lifted.
In "2017", Ken revealed that he has a disappointing son who sells bolo ties on Etsy.
