A plunkist is an adherent to the ill-founded religion of Plunkism. These members were originally G*nkists who fell intertwined dark side teachings into their dietary habits. As a result, mental decline quickly set in, causing them to falsely recreate idols with four legs and large bodies. In turn, Plunk droids were created.
Plunkists are known for their lack of mental ability and short life span. It is possible that Wookiee Goldberg, Darth Darth Binks and Darth Dateline NBC were Plunkists due to their lack of intelligence, unstable persona, and their diet of dark side infused food.
