Momoiro Island is an island in Paradise. It is located close to the Lulusia Kingdom. The island is filled with pink animals and plants. It is home to the Kamabakka Kingdom (カマバッカ王国,Kamabakka Ōkoku?, "Kamabakka Queendom" in the Viz Manga), a place where "those with a heart of a maiden" gather. The name of the kingdom literally translates to "full of transvestites", which is exactly what the island is filled with.
The island and its inhabitants are just as well known as the legendary island of Amazon Lily. However, the islands are exact opposites of each other. While Amazon Lily is comprised only of women who behave somewhat similar to men (similar to the Amazons of lore), Momoiro is filled only with men who behave similar to women (usually the behavior of a transvestite). Even the animals are transvestites. Nevertheless, like its counterpart, the island's population seems to be comprised of powerful fighters who abide and appear to be totally comfortable with their lifestyle, mostly due to their famous power-enhancing Attack Cuisine. The Okama inhabitants held the Revolutionary Army in utmost respect and esteem due to Ivankov's membership, particularly the top executives Morley and Betty, whom they address with the honorific sama and was excited to see them gather.
Sanji was sent here by Bartholomew Kuma during the events of Sabaody Archipelago. Due to the maniacal nature of the transvestites inhabiting the island, Sanji considers the place to be 'Hell', but still spent two years on the island honing his skills.
After the Blackbeard Pirates destroyed Baltigo, the Revolutionary Army moved their base of operations to Momoiro Island. Dragon summoned the revolutionary commanders to this island for a meeting to plan their declaration of war against the World Nobles.
