The hero of Wolf of Little Mice is the youngest mouse of triplets. Mother Mary gave the youngest mouse a long name, Wolfgang Amadeus. He hoped to make the little mouse better with a famous name, but the mouse was laughed at by her brothers and sisters again and again because of this long name, so she wished she had a short name like other brothers and sisters. Later, his brothers and sisters slimmed down his name and called him Wolf. He is satisfied with the name. Later, as they grew up, all mice showed their advantages, but wolves were not good at anything. They are running on the piano, which is the last one, but it has a soft spot for music. Their home is in the home of the old lady Hanibi. Her husband has died and her children have grown up, so the old lady is very lonely. Later, I raised an old yellow cat as my companion. Mrs. Hanibi found Wolf on the piano because Wolf and his mother were stared at by the old lady's yellow cat. Finally, because the piano box fell and hurt the yellow cat's tailbone, they were able to live, but they were locked in the piano. When the old lady turned on the piano, she found Wolff singing from the beginning, but Wolff and her mother fled back to the cave. The old lady was attracted by the singing mouse. She taught the mouse to sing. Give him chocolate, hoping to make friends with mice. Finally, the mouse and the old lady finally face each other on the piano. The mouse cooperates with the old lady to play the piano and sing. Every day, the old lady teaches him new songs. Then one day, according to the normal time, the old lady should come to play the piano, but she didn't show up, so Wolf began to worry about the old lady, so he went to her bedroom. It turned out that the old lady fell and needed an ambulance. But she couldn't get up and could only moan. Seeing that the old lady needed help, the little mouse ran to the windowsill and sang a song. A policeman heard his singing. Alas, when he was about to leave, he heard a strange noise in the house. He knocked on the old lady's door, called an ambulance and saved her. On the way to the hospital, the old lady kept asking him what to do with his cat and his singing mouse. People think he is confused. So I went to the hospital and let him stay in the hospital for a few days. In the days without the old lady, Wolf's mother became very anxious because she missed Mrs. Hanibi, but her chocolate, Wolf missed the old lady more and wanted to sing with her. Later, he began to write a song by himself. He kept practicing and wanted to give it to Mrs. Hanibi. Finally, Mrs. Hanibi came back to sing. Mrs. Hanibi gave them chocolate.
