Humandrill
A humandrill (ヒューマンドリル) is a type of baboon that Roronoa Zoro encountered in Kuraigana Island. They are highly intelligent creatures capable of imitating humans so much that they will mimic any trait they witness. One of the humandrills even used spit to heal its wounds, which is a folklore remedy. If they were to see peace they would be peaceful creatures; however, nine years ago, they witnessed a war on Kuraigana Island, causing them to learn how to wield weapons and become bloodthirsty warriors.

The humandrills are very strong: they were a major obstacle to Zoro when he tried to reach the ocean and they even destroyed the boat that Dracule Mihawk gave him to leave the island. One of them was seen withstanding Zoro's Oni Giri attack without falling to the ground, using spit to heal its wound. Perhaps a great testimony to their fighting strength would be when Mihawk reacted with visible surprise after Zoro revealed that he had defeated them all. Nevertheless, they are afraid of the Shichibukai to the point that they do they not even dare to come near his castle.

In the anime, Humandrills' behavior have been explained greatly than in the manga. They were able to imitate Zoro's santoryu techniques just by seeing them. When Zoro defeated them, Mihawk explained him that he defeated only a part of them and that by imitating the soldier of the war on Kuraigana Island they even imitated their ranks system, thus meaning that baboons organized themselves like a real army. Finally, the most incredible test of their high intelligence is that one of them managed to imitate Mihawk's swordsmanship, even achieved developing a white copy of his sword, the Kokutou Yoru; thus becoming in the leader of the Humandrills army.

Their name is a combination of the word "human" (which they imitate) and mandrills, the type of monkey which they resemble.

Big Tiger
The Big Tiger (大虎) is seen in the forest of Goa Kingdom. It is a very fierce and big tiger that tries to eat young Luffy in the manga and also takes Luffy's "first hunting prize" in the anime. 12 years ago from the current storyline, Luffy, Ace, and Sabo were no match to the tiger, even if they fought together. It seems to be able to handle cold climates since it appears in a snowy mountain before Luffy and the others. The Big Tiger has the ability to attack with it's tail, as shown in the anime. Later on, Luffy, Ace, and Sabo defeat the tiger together after training with Naguri.

Wild Bear
A Wild Bear appears several times in the flashback of Luffy in Goa Kingdom. It's strength, as stated by young Ace, is about the same as the Large Tiger, and it could not be defeated by young Ace, Luffy, and Sabo until Naguri came and forced it back to the forest using Haki.

Domo Penguin
The Domo Penguin (ドウモウペンギン) is a type of penguin that is native to Hyokaido. It generally resembles a blue Rockhopper Penguin with a Puffin like beak. Large groups of this penguin are able to move the various icebergs in Hyokaido from underneath. The Accino Family use these penguins' ability to move icebergs to trap their prey's ship between the various icebergs in Hyokaido.

The penguins themselves are very vicious. Large groups of them can cause trouble for anyone in their way. The Accino Family thus also use the penguins' vicious nature against their prey.

Danpa
Danpa (ダンパ) is shown to be Luffy's "first hunting prize" in the anime (Episode 498) in Goa Kingdom. Its name is a pun with Pandas, and its fur color is opposite from pandas as well; dark where pandas would be white and white where pandas would be dark colored. It is not very strong compared to the Large Tiger since young Luffy "caught" it very easily. Danpas probably don't hibernate, since it is seen running away from Luffy and the trio in a snowy mountain.
