1. First, we need to fly into the clouds along the valley and summer until we see the hillside, where we can find the little prince and get close to him to trigger an animated story.
2. In the process of interacting with him, we can know that the little prince needs us to play music, just playing on the score at will.
3. After triggering a new animated story, the little prince needs us to play another piece of music and click a few times at will.
4. Continue to interact with the little prince after the completion, and the fifth task will be successfully completed.
