Quick recap
Filler arc outside the main line. The crew chases Boss, a giant beetle, to an island that mimics the East Blue, where the locals live in replicas of the towns the Straw Hats passed through and even run a Nami fan club. A girl named Yoko welcomes them. Largo's Amigo Pirates attack the village for the beetle, on orders from a legendary old pirate, Golden Lion Shiki. Largo traps Luffy, Zoro and Sanji with his net fruit, but Boss frees them. Luffy beats Largo with Gear Third, and the crew leaves. The hint left behind: Boss was created by Shiki.
