This rarely seen old mechanic lives just outside the town of South Park with his wife, not far from Conifer. He tries to dispense helpful advice to those he meets, such as a lost little boy named Butters, and a grieving father he suspected was trying to bring his son back to life through unnatural means. His attempts to help others out have often caused more harm than good, and he might not as mentally sound as he appears. He's been known to stop in town at Skeeter's Bar and Cocktails for a drink now and then, dispensing more helpful advice to the citizens of South Park, but he also spends some time up in Aspen to tell tales of the ski runs.
When he's not dispensing advice, he's working as a mechanic at an old gas station, or tending to millions of Member Berries at his farm, though he can't understand the crop's popularity.
