Horn Eaters (ツノクイ, Tsuno Kui) are a type of creature featured prominently in the third One Piece movie. They are large herbivorous armadillo-like rhinos that will aggressively attack any horned creature within sight, even if said creature happens to have fake horns, as seen with Luffy (Usopp had him garbed in a ridiculous costume with antlers included). They are used by Butler to herd the various other horned animals on Crown Island in order to chop their horns off.
Square Rhinos (四角いサイ Shikakui Sai?) are animals with a rectangular form and loosely resemble rhinos that live on the Crown Island. When they lie on the ground, it is very easy to mistake them for rocks.
A Hippo Rhino (カバサイ Kabasai?) is a purple rhino with a hippo's mouth. It can be mistaken for a rock when its head is downwards. It's also a good swimmer as it was able to swim far out to the sea. It fell in love with the Going Merry after it landed on it which made it spit out a fish it was choking on. It decided to swim to the Going Merry and propose to it.
The Island Turtle (シマガメ Shimagame?), also known as Mecha Island, is a giant turtle that wakes every thousand years to lay its eggs. These eggs are considered extremely valuable due to being made of gold.
Heart of GoldEdit
The Water Lizard (水中トカゲ Suichuu Tokage?) is a type of reptile that exist in one of the island swallowed by Bonbori. Two Water Lizards, who are named Elizabeth and Chavez, are adopted by Myskina Olga and her father and now live with them after escaping from Bonbori's stomach.
The Giant Footballfish is fish that roams though the New World. The inside of its body is somehow far larger than the outside, having three stomachs big enough to hold an island. It has a powerful desire to eat the rare Pure Gold and it only surfaces when it senses its light in the sea. Consumption of Pure Gold make the bulb on its head shine a bright golden light. One specimen is Bonbori who is known to have eaten two islands, one inhabited by dinosaurs and the island of Alchemi.
One Piece Film: GoldEdit
Lucky Turtle SquadEdit
The Lucky Turtles are small turtles that were enslaved by Gild Tesoro and made to power the various automobiles, known as Turtle Shuttles, on the Gran Tesoro. After the island was sprayed with sea water and Tesoro was defeated, the Lucky Turtles most likely gained their freedom. They are referred to as Rare Muscle Turtles in the FUNimation dubs.
The Gigant Turtles (ギガントタートル Giganto Taatoru?) are massive turtles nearly a third the size of the Gran Tesoro (which itself stretches 10km long) that were tamed and harnessed to the ship. Two of them are attached to the Gran Tesoro, and are tasked with protection of the ship from Sea Kings and sea creatures that would do the ship harm. Furthermore, they both have what appears to be a massive cannon attached to their back. They are referred to as Giant Turtles in the FUNimation dub.
The Red-eyed Owls (赤目フクロウ Akame Fukurou?) are a species of owls tasked with monitoring a passage way that leads to the Lesoro's Hyper Suite, where a safe containing a fortune lies. The Red-eyed Owls' gaze emits light, and as soon as anything living is caught in their gaze, they will scream and alert security. However, their gazes move at set intervals, so it is possible to avoid the lights, especially if one can understand their speech.
A ferocious species of bats that guard the pipeline to the Gran Tesoro's saltwater pump. Although they may prove formidable to normal people, they were instantly defeated when faced against the likes of Luffy and Franky.

The powers and abilities of a dragon are so strong that not only can it destroy a single town (under the control of D.R. and Cyrano with the use of a Dragon Horn) and bring terror to the public, but killing one made the samurai Ryuma a legend, and stories about him are still passed down after generations.
Dragons were first mentioned by Hogback in the One Piece storyline during the Thriller Bark Arc, where he revealed to Zoro the story of Ryuma and his legendary slaying of a dragon long ago which the latter took in with much skepticism.
Dr. Vegapunk was revealed to have created his own artificial dragons to guard Punk Hazard. The Straw Hats encountered two, both of which were incredibly strong, and one possessing great speed as well. However, both were eventually killed by Kin'emon and the Straw Hats.
