What does it mean when a magpie drinks cola and turns into a crow?

This sentence is the first sentence of the acrostic poem. The original text is: I heard that if a magpie drinks too much cola, it will turn into a crow. If you say welcome too much, it will turn into thank you for your patronage. If your cat loves you too much, it will turn into a rabbit. I have also heard people say that it will turn into a rabbit because it is too shy. What you say is hidden at the beginning of the sentence.

Other acrostic poems are as follows:

1. There is a wasteland in my heart. I am happy that the sky is clear and there is no rain. You are the god of that day and the earth.

2. I am a seven-star ladybug who likes the breeze and sunshine. You happen to be a leaf among thousands of trees.

3. I heard that Xizhilang's orange flavor is delicious. Listening to happy songs will actually make you happy, and you won't find that it is an acrostic poem.

4. When I wake up, I like to lie in bed. I am so happy that I picked up my phone and you just happened to send me a message.

5. I don’t know how to tell you. How do I say that I like this kind of thing? You have to be careful to enjoy yourself secretly. Wouldn’t you read the poem vertically?
