Anime and Manga Differences

 * When Mohmoo recognizes Luffy in the anime, he remembers when Luffy punched him with Gomu Gomu no Pistol the first time they met. However, in the manga, Mohmoo remembers when Luffy used Gomu Gomu no Kazaguruma to defeat him and some of the Fishman Pirates at Arlong Park.
 * Franky didn't explain that they cannot use Coup De Burst to Nami.
 * A photograph of Kokoro can be seen with the pictures of Nami and Robin in Sanji's possession.
 * Robin's sketch of the Kraken is shown in the anime. It was not in the manga, but it was shown in SBS Volume 63.
 * Chopper does not use the Rumble Ball to activate Guard Point. It could be to correct the error of the manga.
