When Pi is on the island he is happy, but somehow the many mysteries of the island begin to suggest that maybe the island is not entirely safe. Identify 2 things in this chapter that appear to be warnings and explain how the island may be bad

Pi finds a tree at the center of the forest that appears to be the only tree to have fruit. When he tries to eat the fruit, he finds that each piece of fruit is actually layers and layers of leaves wrapped tightly around a human tooth; what's more, together the fruit form a full, perfect set of teeth. Pi’s curiosity gets the best of him, and he tries to plant his feet on the island by night. The soil burns him terribly, however. It turns out that the island is carnivorous: it emits acid at night that dissolves anything on its surface.
