The Troublesome Pigs

The Naughty Pigs or The Pigs. They are one of the main antagonists in Shaun the Sheep, housed in a yard next to the sheep’s field, the Naughty Pigs are the bane of Shaun’s life.

Personality
Mocking, cantankerous and greedy, they're always trying to antagonize The Flock and get no greater pleasure than disrupting Shaun’s schemes – though they are far too lazy to come up with any good ideas for themselves; even they laugh at Shaun when he gets hurt. They are, however, scared of Bitzer, who puts them in line. They are bullies to Shaun and his flock, and they got told off in "Pig Trouble" (Series 2) by the farmer. They own a car (The Big Chase) and an airplane (Pig Swill Fly). Their birthday is unknown (in Series 4 their birthdays are known and their age is still not mentioned). On the rare occasion, such as in The Phoney Farmer, they'll actually cooperate with the Flock. They broke into the farmer's house and did bad behavior, eating his food and taking pictures of themselves on the camera.

Interesting to note, the pigs also exhibit extreme levels of hand eye coordination, hinting at a much more elaborate past than what the canon lore of the series has presented. Of particular interest is the time when they wreck the farmer's house after days of hard partying. What seems like an unfixable, destructive mess, is fixed in a matter of seconds, with windows being replaced, complex paintings re-done, and advanced cleaning manuevers carried out. Such skill can only point to one end. The pigs were once associated with the masons. Although hard to fanthom, it can be the only explanation to such expertise around the home and mastery of power tools. Look within your heart reader, you know it to be true.
