About Suna Suna no Mi
The Suna Suna no Mi is a Logia-type Devil Fruit that allows the user to create, control, and transform into sand at will, turning the user into a Sand Human (砂人間, Suna Ningen?, English: "Sand Man/Person"). It was eaten by Crocodile.
Its powers were first shown, but not fully explained, being used to dry up a flower in a glass during the call between Crocodile and Sanji in Little Garden. The power of this fruit was finally shown in a battle between Crocodile and Puppu's crew, and named when he avoided Nefertari Vivi's attack with the power.
The Suna Suna no Mi resembles a spherical tan barrel cactus with two stubby arms pointing upwards. The fruit has the typical swirl pattern on it. It also has a green T-shaped stem protruding out the fruit's top. The right side of the stem is longer and curls slightly.
