Four Wise Men (カエル四賢者,Kaeru Yonkenja?, literally meaning "Four Frog Wise Men") are four elderly, tiny members of the crew, each with a frog-like appearance, hence their group name. Despite this, one of them is female. They consist of Kerojii, Keroko, Keroshot and Kerodeek.
With the exception of the captain, Baron Omatsuri, the crew was annihilated by an enormous storm which later beached the remains of the ship atop the shore of a secluded island. This island sooner became a "pirate only" resort intended by Baron Omatsuri to separate entire pirate crews whose men would be used to fuel the illusions created by the Lily Carnation - a mammoth plant revered as the flower of death and rebirth. The remaining distinguished Red Arrow crew mates, Muchigoro, DJ Gappa, Kotetsu, and the Four Wise Men were integral parts of the illusion, and were kept alive as plant hybrids developed by the Lily Carnation. Following the destruction of the Lily Carnation, the illusions are dispelled and the Captain is put to rest by Monkey D. Luffy.
A wanted poster of the crew is seen, but the number is partially hidden. However, there are six zeros visible on the poster, so it can be inferred that their bounty is in the millions.
