Mocking, cantankerous and greedy, the pigs are always trying to antagonize The Flock and get no greater pleasure than disrupting Shaun’s schemes. They are, however, scared of Bitzer, who puts them in line, and even more deeply terrified of the Farmer's wrath. While they are bullies, the pigs are highly intellegent and physically capable. They are capable of operating vehicles, such as a car (The Big Chase) and an airplane (Pig Swill Fly), and are capable of plotting elaborate schemes. On the rare occasion, such as in The Phoney Farmer or Duck!, they'll actually cooperate with the Flock, if begrudgingly.
After Shaun and the Flock travel to the city in search of the missing Farmer, the Pigs being partying in the lost Farmer's home, utterly destroying it. Later, when the Flock has successfully brought the farmer home, they immediately panic and begin restoring the damage caused.
- Unlike most animals in the series, the pigs have never been seen walking on all four legs.
- Unlike The Flock, the Pigs are always shown in a set amount of three, though they are never established as individuals.
