Mysterious sounds outside the camper

Last night I woke up to some interesting noises. I would hear a dull crack followed by what sounded like an old man snoring while having very unpleasant dreams. It sounded like the action was happening right outside my window for a few minutes, but then it slowly faded away and I fell back asleep. 

In the morning I asked Yan about the noises, and he knew exactly what I had heard; pigs cracking open  macadamia nuts. Yes. Wild pigs, cracking shells of the gourmet nut typically paired with white chocolate, at 3 in the morning. Apparently, there's a cluster of the trees right outside of the camper. Apparently, pigs like macadamia nuts. Just rooting around for a late night snack! Who knew?
