You can get all the another pigs follow you by holding wheat. You have a sword, 64 wheat and 7 cooked porkchup. I suggest to play the game on peaceful, because it is dark in some parts of the arena.
There are also chests in the Arena, with some items in it. If you found Flint and Steel, you may burn wool. If you found shears, you may cut the leaves of the trees away. In every chests are gold nuggets, the number of nuggets you have, when you finished the game, is your score.
Here are some screenshots of the Pig Runs Arena:
