A detailed 3D model of the Gura Gura no Mi (Quake-Quake Fruit) from One Piece, shaped like a cube. The fruit should have a slightly bumpy, matte surface with bright, glowing cracks and fissures running across all sides, similar to glowing lightning or energy. The base color of the cube should be a light blue with darker blue swirling patterns underneath the cracks. The stem on top should be a light green, leaf-like shape.
