Compared to the airplane we saw on the island earlier, this wreckage was much older, covered in vines and plants.
This was why I hadn't noticed it after walking for so long. I tried to look more closely, and the model of this old-fashioned plane further confirmed my suspicion. It looked like a World War II model.
'Could it have been left by the people stranded on the island during World War II?' I wondered. I carefully examined the area around the plane wreckage. Sure enough, I soon made another discovery!
It was a treehouse! Hidden among dense plants, the lush foliage nearly concealed the treehouse, revealing only a faint outline.
If it weren't for my keen observation, I would never have spotted it. This treehouse indicated that someone lived at the bottom of the sinkhole!
