One Sunday afternoon, when the interest class was over, the students all gathered around the pool of the neighbor's grandfather's house. I squeezed in curiously and saw many tadpoles swimming around happily in the pool. Grandpa saw that we liked tadpoles so much, so he said, "Take whatever you want." We scrambled to catch tadpoles, and I also caught two tadpoles and prepared to take them home. On the way home, my mother teased me and said, "How about I have two toads?" I replied, "No, tadpoles become frogs, and toads are toads."

When I got home, I kept tadpoles in a basin on the balcony. I go to see it every day, but for two or three days a day, the tadpoles haven't changed, and I gradually forget it. Suddenly one day, my father-in-law shouted from the balcony, "Yuan Yi, Yuan Yi, come here quickly." I rushed over and saw a little tadpole with two slender hind legs. A few days later, the tadpole grew two front legs, its tail became shorter and its round head became sharper. Unconsciously, the tadpole turned into a frog, eager to jump out of the basin. Does it want to find its mother? I put the frog back into nature, hoping that it can find its mother and help farmers catch pests with her.
