Mandrillium is a part completley unobtainable, only being able to be spawned/crafted in unstable. Mandrillium appears to be a 2x2 cube with a texture of a Mandrill face (a monkey species) on all sides. This form only lasts for a split second, as then it turns into a maze around 1/4 the size of the Testing Zone baseplate. The maze walls are textured with only the same Mandrill face, and the floor of the maze is coloured Oyster (may be wrong).
