Selkies are mythological creatures associated with water. Some seem to have similarities to Sirens, also having an alluring song.
In the Final Fantasy Crystal Chronicles video game series, Selkies are human-like agile creatures with odd hair colors, including baby blue, pink, and green. They are the only race capable of double-jumping. In some games they use bows, while in others they use what appears to be tennis rackets.
The king in Final Fantasy Crystal Chronicles Rings of Fate is a Selkie, and his daughter is a Selkie-Clavat mix.
