How did they "create" a samurai face, as opposed to it simply being an anomaly?
By choosing to throw back those that looked like samurai.

Heikegani (samurai crabs) were used by Carl Sagan in his popular science television show Cosmos: A Personal Voyage as an example of unintentional artificial selection.
I should point out that in the case of psychoactive plants used by humans, artificial selection played a role, too. A big one.

Human beings are much larger and can process these poisons better than smaller creatures, which for them, will kill them quickly.
Very small quantities of poison can kill us too. Black widow, Brazilian wandering spider, death cap mushroom, stone fish, golden poison frog, death lily, Japanese pieris shrub ... the list goes on and on.
Thru trial and error, we figured out which ones felt good and didn't kill us. Simple as that.
