Dan's father owns a spa resort on Route 1, which is famous for its sand baths. He works there with his son Dan. He first appeared in a flashback, where Dan told Ash and Iris about the Sandile incident that had been occurring quite often for a few days, which has been scaring customers away.
Later, Ash, Iris, and Dan found out that the reason the Sandile were scaring the people away was that the geysers were dangerously close to erupting. Soon after, it was revealed that the geysers had done more good than harm and put Dan and his father back in business with a brand-new hot spring, which he treated Ash and Iris to.
