Anime and Manga Differences

 * In the anime, there are some scenes that are a little stretched such as the scene of the Fishman Island citizens giving Otohime their signatures. The pace of the anime initially made ​it seem that citizens would not give their signatures.
 * Otohime is shown trying to save the signatures in the anime.
 * In the manga, when the gun that shot Otohime fired, a soldier heard it and asked what was that. This wasn't shown in the anime.
 * In the manga, after Otohime got shot, she was in the arms of the Minister of the Right until the time of her death. In the anime, she was first in the arms of the Minister, but was then caught by Fukaboshi and a little later placed on the floor.
 * In this episode, neither Keimi, Pappug as kids and the fishman who like how Luffy first drew a Nami-looking fishman appears.
