What does toad mean in ancient poetry?

In ancient mythology, there were toads in the moon, so the moon was called toad and the moon was the moon palace. In addition, toads are endowed with the function of avoiding weapons. In the Ming and Qing Dynasties, when choosing the theme of toad, bamboo people skillfully used the nodules on bamboo roots as toad eyes, with specially carved back protrusions, which was very clever.
