I made Ninja amigurumi before, the crocheted and the knitted ninja.
and for the third time, I made Ninja for my alphabet amigurumi series.
why not? I love Ninja games, I played Ninja Gaiden and Shinobi
I haven't watch any Jaka Sembung (The Warrior) movie,
but I remember it has a sequel The Warrior and The Ninja,
and I think it would be interesting to put the Ninja and Jaka Sembung in the scene together.
fyi, the ninja design is not based on the movie of course
