It is recommended to look at it from different aspects~
For example: eyes, mouth, ears, or movements and expressions. Choose a name that is symbolic and easy to remember.
If it were me, I might consider something interesting or good-sounding, such as: blueberry (the color also symbolizes being as cute and watery as blueberry, and the homophones are also quite good: blue rose, blue plum)
p>Or Lingche (it means that the eyes are very clear and watery...)
etc., all are fine. It depends on personal preference.
