This can be either a quad or bonus monster for the final island. Sound: It makes a sort of autotuned voice using that synth wave and the cannons make percussion sounds (I can make the sound if you want me too) The empty bit at the top is the pilot seat, I don't know if The Rasguno's built this to battle Kubbel/Accimant or Kubbel/Acciman build it to fight the Rasgunos.
