In appearance, the Clever Cube is a cubic-shaped helmet with several square patterns on the sides and top of the mask. Each square-shaped plate appears to be made out of glowing purple stones and other purple gemstones/minerals. Two 'white eyes' can be seen on the front of the mask, as well as an open breathing hole (mouth) at the center of the mask.
Once equipped, the players will receive 10 armor points, slightly increasing their protection. They will also receive 60 additional points to all damage-types, increasing the number of damage inflicted on opponents while using any weapons.
- The Clever Cube is one of the many items with the word 'Cube' in its name. Other examples include but are not limited to the Concentration Cube, Century Cube, and Freedom Cube.
- The Clever Cube's square pattern above the face of the mask shares a similar pattern and color scheme of a Whapper Board.
- The Clever Cube is one of three "cube" headpieces that provides increasing amounts of armor and all damage types. The other two cubes are the Kitchen Cube and the Century Cube.
