Kerojii

The Four Wise Men (4つの賢い人) are four tiny, old, frog-like members of the Red Arrow Pirates who appeared in the sixth One Piece movie. Despite their group's name, they are not all men.

They consist of Keroji (ケロジイ), Keroshot (ケロショット), Kerodeek (ケロデーク), and Keroko (ケロコ). In the movie, they participated in the second Trial of Hell issued by the Baron Omatsuri against the Straw Hats.

Three of them anger Nami just after being introduced: Keroji believes that they are much wiser then the Straw Hats because of their age.

Keroshot calls her immature for getting angry. And Keroko insults her by saying she's only a little younger then herself.

The only member that did not take a hostile note to the Straw Hats upon introduction was Kerodeek, who just asked if he could take a nap.
