Gyoro, Nin, and Bao

Gyoro, Nin, and Bao are a trio of oddly shaped zombies that were first seen reporting to Moriah about the Straw Hats' arrival.

Appearance
They are relatively small zombies that are roughly the same size as Chopper when he is in Brain Point. Gyoro is the zombie that looks like a one-eyed samurai with an ovular head. Nin is the pinkish-red zombie archer with a triangular head. Bao is the yellow zombie that looks like some sort of super hero with a bucket shaped head.

History
They reported to Moriah, with the archer shooting one of Moriah's snot bubbles to wake him up. They later reported the arrival of the Mysterious Three when they arrived as per Moriah's request. After extracting Luffy's shadow, they were then ordered to open the way to Oars by Moriah. They then accompanied their master to the 900th zombie.

Their shadows have been taken from them like the other zombies to upgrade Moriah.

Trivia

 * "Gyoro" is the sound effect of when people stare at something with big eyes, which somewhat suits his looks.
 * Nin may be referring to a ninja.
