"King snake," then I felt the nikyo. ...
My husband explained to me recently that there is indeed a King Cobra. I didn't even know that, but there was no doubt Masuda Sensei was imitating a cobra.
Sorry to go OT but I don't like to let critter information go awry...
There is a king cobra, but a kingsnake is not a cobra.
Kingsnakes are a large group of constricting snakes. They are commonly kept as pets.
The use of the word "king" to describe any snake, BTW, be it the kingsnakes OR the king cobra, means that it is a snake that eats other snakes
