What beast is this?

Judging from your words and pictures, the animals you are talking about should be four elephants. Although this animal is a mythical animal, it is also very brave and admirable. Just like his appearance, it is a combination of four animals, so it is called four elephants.

Just like Jiang Taigong's four unlike mounts, he is, like four animals, but it is an animal, so it is called four unlike, four unlike, almost the same, or the opposite. It depends on what color the author gives them.

If you look at the picture, it should be the legendary Xuanwu. Only Xuanwu has a turtle body, a dragon head and a dragon tail, and a snake body. When you see the picture, you are talking about the legend of the four elephants.
