I write about the movie, "Mirage".
In Mirage, main character is an android. He can pool water in his body.
his energy is got by water. if he loses water, he may die.
He always needs water. he looks for water. But, he has trouble in getting water.
In the end of story, he finds fruit containing much water. A fish live in the fruit.
He get water from the fruit and feed the fish in his body.
He dreams that he swim in water.
The symbol of this story is water. In my opinion,the android means human being and the fish means animals except for human beings. I assume the author tell us that water is important ,human beings should use water carefully and share water with animals.
