Lapins

Lapin (ラバーン) is the name to a giant race of carnivorous rabbits residing at Drum Island who are defensive of their young. Luffy and company are defeat an aggressive child Lapin in self defense, but they struggle against the angered Lapin parent. The avalanche caused during the struggle buries Sanji and the Lapin parent. When Luffy notices the Lapin child struggling to dig its parent out, he rescues the Lapin parent.

Later, when Luffy is alone against Wapol and struggles to protect a severely ill Nami and an unconscious Sanji, a group of Lapins comes to their aid to repay the debt of kindness. The selfless act apparently causes the wild animals to trust humans. By the time the Straw Hats leave, they are content to coexist peacefully with Drum Island's residents.

Fighting Style
They have the strength and physique of a bear, but they retain the nimbleness of a normal rabbit. Lapins attack by smashing their paws into the ground like fists or by biting with their sharp fangs. They can use their weight to hop in one place and cause an avalanche.
