Karoo

Karoo, also known as "Carue", is Vivi's pet spot-billed duck and one of the fastest modes of transportation in Arabasta. He leads the Super Spot-Billed Duck Squad and is fiercely loyal to Vivi and her friends, the Straw Hat Pirates. While often providing comic relief, Karoo plays a crucial role in assisting Luffy and Usopp against Baroque Works agents and rescuing Vivi from Mr. 2 Bon Kurei.
