The Scarecrow is the main antagonist of a segment of "Terror Tales of the Park III" in Regular Show. He appears in Muscle Man's horror story.
He was voiced by Mark Hamill.
The Scarecrow is a normal scarecrow that does not care about what goes on around him. But if anyone attacks his wife (who is also a scarecrow), then he will get revenge on her attackers. He is vengeful, sadistic and homicidal, as he pursue his targets and kills them off. Despite, the scarecrow's serious nature, he is shown to have a sensitive side when it comes to finding another woman that was like his wife.
The Scarecrow first appears near a cornfield when Mordecai, Rigby, Muscle Man, and High-Five Ghost arrived there wanting to smash pumpkins. Even though Rigby read the warning sign about not smashing the pumpkins, Muscle Man sadistically smashed one of the pumpkins. Enraged over the death of his wife, the scarecrow grabbed High-Five Ghost, turned him into a pumpkin, and smashed the pumpkin. Frightened and terrified, Mordecai, Rigby, and Muscle Man ran off. One by one, the scarecrow found Mordecai, Rigby, and Muscle Man by killing them all and taking their pumpkin seeds to be planted in the pumpkin field. Couple days later, the scarecrow was happy to see his victims as fully-grown pumpkins that will be sold.
