Wow. This episode was really good.
-Great animation and bright colors.
-Naruto is Sabo?!! Believe it!
-The implied filler parts were a great way to pad out the episode.
-Luffy's lying face in the anime is better than in the manga. That is all.
-Porchemy beating the snot out of Luffy was very gruesome and hard to watch.
I guess when it comes to flashbacks, Toei can handle it very well. Unbelievable.
