Arc 1The Farol Islands Campaign
Mousse helped Katakuri and the Charlotte siblings develop their abilities, then joined them in defending the Farol Islands from a Navy invasion. After Katakuri defeated Borsalino, the Charlotte Family considered taking the islands under its protection as the Navy raised Katakuri’s bounty to 1.5 billion Berries.
- Mousse ate the Book-Book Fruit, demonstrated its ability to memorize and control books, and persuaded Charlotte Linlin to let him investigate her gigantification using her parents’ blood.
- Katakuri brought Mousse and a crew of Charlotte siblings to the Farol Islands, where Mousse helped Cracker, Katakuri, Brulee, Oven, and Baron Tamago improve their abilities.
- Katakuri’s crew learned that the Navy planned to destroy Faros Kingdom, so Katakuri and Oven attacked the Navy forces and defeated its officers and soldiers.
- Katakuri fought Borsalino with Mousse’s help from Zeus, whose thundercloud disrupted Borsalino’s elementalization, and Katakuri eventually wounded him badly enough to force his retreat.
- Katakuri and Mousse learned that Charlotte Linlin’s mother had died, while King James Glenn asked the Charlotte Family to protect Pharaohs Kingdom from another Navy attack.
- Mousse urged Katakuri to secure the Farol Islands, arguing that their resources could strengthen the Charlotte Family and help build relations with Elbaf, while Katakuri worried about provoking the Navy.
- Mousse advised Katakuri on strengthening the family’s fighters and using Brulee’s Mirror World to fight or retreat on favorable terms, while Katakuri resolved to protect his siblings.
- Borsalino told Fleet Admiral Kong that Katakuri had defeated him, and Kong raised Katakuri’s bounty to 1.5 billion Berries after learning that the Navy warships had been wiped out.
