Farmer Sprout runs Sprout's Organic Farm on Circle's line.
Farmer Sprout grows vegetables to take to market and is passionate about getting his job done. He's very friendly and approachable to everyone else and likes to help out. He is very charitable, donating any vegetables he can to the nature reserve and letting Mr Rails use his old wheelbarrow for a project.
He wears a red and green checkered shirt over a white vest, with dark green corduroy trousers and black boots.
