The bird landed on a wooden log floating around in the water. It was going downstream. “Um, this wooden log gives me the best sailing experience,” the bird thought.
Further downstream, the wooden log will reach a waterfall. Before that, the bird has to fly away, or she will also fell with the wooden log and die. But the bird, obviously, is not aware of the kind of situation is sleeping.
“Hey wake up from your dreams, you are in danger!” Suddenly, another bird flying above the sailor bird tweeted. The sailor bird woke up from her sleep and saw that she was fast approaching a waterfall. The bird abandoned the wooden log and flew away. She thanked the bird who saved her.
