first: add one piece based structure's and here are a few idea's. the sky island's where you can find a cloud with a house that has a door and when interacted with it send's you to a different place in the same world which is sky island. add more form's to other fruit's such as. gum gum fruit get's gear 5 and "ope" fruit get's more ability's such as a sword that only appear's when a ability is used and leave's the second it's gone like gamma knife. make more of a story line to the mod like in the show such as you go to a quest giver named "nami" and she say's please defeat arlong he is attacking my people or something such and then once your done your bounty increases and you can progress more. that's all thank you.
