The fish dragon thingy... (Score 1)

That fish dragon thing is actually a Chinese sea monster that has the head of a tiger and the body of a fish. The body is covered with poisonous spikes. On land it can transform itself into a tiger. A representation of the Shachihoko was used in medieval Japan as a gargoyle and is what adorns the top of Nagoya Castle in Nagoya, Japan.

Totally unrelated, but thought someone might actually be interested in knowing this.
