RD/KP03-JP012 Ojisan | Old Man Goatfish
WATER, Fish/Normal, Lv 5, ATK 1600/1600
A weary goatfish. It is at the point where it can’t shake off much of its exhaustion.

Note: “Ojisan” can be either an informal way to address someone much older than the speaker, like one’s uncle or grandpa, or refer to the ‘manybar goatfish’, a fish that lives in the seas from Australia to Japan.
