Muyu

The name is a reference to the eponymous wooden block instrument from China.
I picked this name because of the Water-themed scene, skin, and familiar.

"Although wooden fish originated in China, there are many tales associated with its invention. One Buddhist legend says that a monk went to India to acquire sutras but on his way he found the way blocked by a wide, flooded river. A fish offered to carry the monk across the river because it wanted to atone for a crime it had committed when it was a human. Its simple request was that on the monk's way to obtain sutras, he should ask the Buddha to guide the fish on a method to attain Bodhisattvahood. The monk agreed to the fish's request and continued his quest. On his return to China after 17 years with the scriptures, he came upon the flooded river. The same fish asked the monk if he had made the request to Buddha but the monk said he had forgotten. The furious fish splashed him into the river. A passing fisherman saved the drowning monk but all the sutras had been lost in the river. Filled with anger at the fish, the monk made a wooden effigy of a fish head which he beat with a wooden hammer. To his surprise, each time he hit the wooden fish, it made the sound of a Chinese character. He became so happy that he beat the wooden fish regularly. After a few years the monk had got back the lost scriptures he had lost to the flood from the mouth of the wooden fish." (Source: Wikipedia)
