A somewhat old animated Japanese fairy tale

It's not long, so I suggest you check it out. Don't ask blindly.

Ernest Hemingway's The Old Man and the Sea is set in Cuba in the mid-twentieth century. The main character character is an old fisherman from Santiago and the supporting character is a child named Manolin. The old fisherman had not caught a single fish for eighty-four days in a row, and was almost starving to death; but he still refused to admit defeat and, full of the spirit of struggle, finally caught a big marlin of eighteen feet in length and 1,500 pounds in weight on the eighty-fifth day. The big fish dragged the boat towards the sea, but the old man still pulled on the boat, even though he had no water, no food, no weapon, no helper, and his left hand was cramped, he was not discouraged at all. After two days and two nights he finally killed the big fish and tied it to the side of the boat. But many small sharks immediately came to seize his booty; he killed them one by one, and at last only a broken tiller remained as a weapon. As a result, the big fish were still being eaten, and eventually the old man dragged back a set of fish bones in exhaustion. He returned home to lie in bed, had to go from the dream to retrieve the good old days to forget the cruel reality.
