A millipede robot appears as a large, long, robotic-like centipede.
The thirty-segment worm (twenty-nine excluding its tail) moves slowly down the screen, turning-down when it meets the edge of the screen. When it comes down in the way of the player, it will not move down, but instead go off the screen. The millipede robot has no attack. It is only dangerous if it touches the player. The player can only destroy the robot when it shoots its tail once.
Since the robot comes slowly down, it seems to be that the millipede can fly or somehow levitate itself.
