Shaun the Sheep: The Beast of Mossy Bottom

During the leadup to Halloween on Mossy Bottom farm, the Farmer accidentally destroys his sheep flock's secret pumpkin patch. Shaun becomes a mad scientist to fix the problem, creating a potion to regrow the pumpkins overnight. The potion ends up in the hands of the Farmer, mistaking it for a hair growth serum, which he applies all over, hoping to impress the town vet, whom he has a crush on. The potion causes the Farmer's hair to grow wildly out of control, turning him into a shaggy beast resembling Bigfoot. While going through Mossingham, the Farmer inadvertently scares the townspeople, who chase him into the woods, while his dog Bitzer tries to track him down, unaware of his transformation.
