Write a composition about what adventure?

I am an unlucky watermelon seed, which was swallowed by an careless child. I went straight to the esophagus and went down the watermelon juice. Through the esophagus, I came to a "big bag", which is actually a "food storage room" rather than a big bag. Needless to say, everyone must know that this is the stomach. I was really uncomfortable in the "splash and goo east" of my stomach, and rolled back and forth, but fortunately I was not "stuck" and digested by gastric juice, because my stomach could not subdue me. I was walking. Suddenly, I saw a "passage". At first glance, I had no choice but to jump into this "channel"-the small intestine. There are many villi in the small intestine, which work like antennae and absorb nutrients. I accidentally touched a lot of tentacles. "Help!" These hairs want to suck me away, and I think to myself: What can you do to me? The tentacles gave up. I walked around the large intestine for a while. It's not fun here Much better than the small intestine. I think of the large intestine, not far from the anus, and I can see the light of day again! Finally came to the anus. I had to pinch my nose, and then I was discharged with some yellow mucus.
