Pigs are a type of pet that is obtained during Bringing Home the Bacon. They are the children of Pigzilla, and before becoming pets they are known as Pigzilla pigs.
Their names can be customised by talking to Martin the Master Gardener in Draynor, and their appearances can be swapped among three different varieties by changing the type of the pack pig machine in the storm cellar underneath Falador farm.
If the pig is lost, released, or stored in a menagerie, players may retrieve him from Eli underneath Falador farm.
- The players can rename their pig Harry Trotter, in reference to Harry Potter.
- One of the several names players can give their pig by talking to Martin the Master Gardener is Napoleon. This is a reference to George Orwell's Animal Farm.
- Two of the possible name combinations "Derek Trotter" & "Albert Trotter" are a reference to the British sitcom Only Fools and Horses. The name "Harry Trotter" could be a reference to the show, due to it being mentioned in an episode.
