Farmer

Mr. Douglas is a character of the day who appeared in The Whistle Stop (EP130). He was not given a name in the Japanese version.

He is a farmer working at an apple orchard. He received help from Arielle, who pollinated the apple trees with her Ledyba. Mr. Douglas made a brief appearance when Ash, his friends, and Arielle visited the apple orchard. He drove past them on his tractor to greet Arielle before driving off.
