One Piece - Episode of Nami
I started watching this because I was bored, and I have to say that I was glad I was bored. It was a really nice special, and really summed up the Arlong Arc in a nutshell. It took all the comedy parts of the arc out like when Luffy put Arlong's teeth in his mouth or Usopp being chased by Choo for a very long time (they shortened this part up a ton which I'm glad because it lasted like 2-3 episodes). I kinda liked that to be honest, it really made it more dramatic and powerful.
Animation was really good, and holy moly at that Sanji kicking part. They really outdid themselves on Sanji and Zoro's final attacks on their fights! Luffy's looked cool too, actually his was the best.
Sometimes I always forget just how bad Nami's past is, but seeing this really reminded me of that.
One Piece Nami Fan-Service Special (Glorious Islands)
I heard this was a special 15min special pre-quel of Film Z so I gave it a watch.
First off this isn't really called Nami Fan-Service Special, but that's really all it is. It's just 5mins of looking at Nami in a swimsuit, 5min of watching Franky, Luffy, Zoro, Brooke, and Chopper imagining food, and 5min of Usopp, Sanji, and Robin discussing Usopp's new invention. Nothing great but it was still a nice little Strawhats antics special on their ship.
