One Piece episodes 9-17: Eight episodes to tell the story of Luffy's third crew member. I'm guessing they were commissioned for a lot of episodes from the start, as this could have been told in two episodes if it wasn't for all the intro's, previews, reviews, recaps, flashbacks, and extended emotionally tearing scenes. That Captain Kujo was a nasty piece of work, wasn't he? And his glasses got smashed at least twice in the fighting.
At least they have a proper boat now.
