As it belongs in Early Poptropica, the pig's design appears to be 8-bit-a pixelated look-like the people in the little town of Early Poptropica.
Sometime before the player finds the island, the Pig was stolen by the Giant Spider. Luckily, the player (you) came and took it back to its owner, the Farmer. Its owner also hinted that he might soon slaughter the Pig and cook it. (A "Porker" is a pig raised for food.)
