Once Huey and Siria have reappeared at the bottom of the screen, they'll start moving forward again for a fifth time (faster than the four previous stages) as they come to two Fire Flowers that are firing projectiles at them from their position on that wall on the left side of the screen; once you've shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at both of these, to kill them, you will come to three more Fire Flowers that are firing projectiles at you from their positions on the wall on the right side of the screen. Once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, you will come to two more Fire Flowers that are firing projectiles at you from their positions upon the wall on the left side of the screen - and once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at both of them to kill them, you will come to three more Fire Flowers (the eighth of which is flashing) that are firing projectiles at you from their positions on the wall on the right side of the screen. Once you've shot off Black (or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, the eighth one will send one randomly-generated powerup flying towards Huey and Siria; once you have collected it, it will take its effects upon Huey (or Siria). You'll then come to three more Fire Flowers (the eleventh of which is flashing) that are firing projectiles at you, from their position upon the wall on the left side of the screen - and once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of these, to kill them, the eleventh one will send another randomly-generated powerup flying towards Huey and Siria. Once you have collected it, it will again take its effect on Huey (or Siria); you'll then come to an Iron Wall in the centre of the screen. Once you have shot off a Black (or Green, or Orange, or Level-2, or Level-1) flame at it to kill it, you will come up to three more Fire Flowers (the twelfth of which is flashing) that are firing projectiles at you from their positions on the wall on the left side of the screen. Once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of these, to kill them, the twelfth one will send off third randomly-generated powerup flying towards Huey and Siria - and once you have collected it, it will once again take its effects on Huey (or Siria). You'll then come to three more Fire Flowers, that are firing projectiles at you, from their positions on that wall on the right side of the screen; once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, you will come to three more Fire Flowers that are firing projectiles at you, from their positions on that wall on the left side of the screen. Once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, you will come up to three more Fire Flowers that are firing projectiles at you from their position on the wall on the right side of the screen - and once you've shot Black (or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, you will come to three more Iron Walls in the centre of the screen. Once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of these, to kill them, you will come to two more Fire Flowers (both of which are flashing) that are firing projectiles at you, from their positions on that wall, in the centre of the screen; once you have shot off a Black (or Green, or Orange, or Level-2, or Level-1) flame at both of these, to kill them, they'll send two more randomly-generated powerups flying towards Huey and Siria. Once you've collected them, they will yet again take their effects on Huey (or Siria) - and you will then have to choose either the left or right path, much like Amul did in the final stage of the original Dragon Spirit arcade game on three occasions back in 1987. You will encounter something different on both sides of the centre wall.
If you chose the left path, you'll come to four more Fire Flowers (the twenty-ninth of which is flashing) that are firing projectiles at you from their positions upon the wall on the right side of the screen; once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, the twenty-ninth one will send a sixth randomly-generated powerup flying towards Huey and Siria. Once you have collected it, it will for the fifth time take its effect on Huey (or Siria) - and you will then come to a fifth Iron Wall, in the centre of the screen. Once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at this to kill it, you'll come up to three more Fire Flowers (the thirty-second of which is flashing) that are firing projectiles at you from their positions on that wall on the left side of the screen; once you have shot off Black (or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, the thirty-second one will send off a seventh randomly-generated powerup flying towards Huey and Siria. Once you have collected it, it will for a sixth time take its effect on Huey (or Siria) - and you will then come to a thirty-fifth Fire Flower, that is firing projectiles at you from its position on the wall on the right side of the screen. Once you've shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at it to kill it it'll explode; however, if you chose the right path, you will come to two more different Fire Flowers, that are firing projectiles at you from their positions on that wall on the left side of the screen. Once you have shot off a Black (or Green, or Orange, or Level-2, or Level-1) flame at both of them to kill them, you will come to a different fifth Iron Wall in the centre of the screen - and once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at it to kill it, you will come to four more different Fire Flowers (the thirtieth and thirty-second of which are flashing) that are firing projectiles at you from their positions on the wall on the left side of the screen. Once you've shot off a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of these, to kill them, the thirtieth and thirty-second ones will send two more different randomly-generated powerups flying towards Huey and Siria; once you have collected these, they will for a fifth time take their effects on Huey (or Siria). You will then come to two more Iron Walls, in the centre of the screen - and once you have shot off Black (or Green, or Orange, or Level-2, or Level-1) flame at both of these, you'll come to a thirty-sixth (or thirty-third) Fire Flower, that is firing projectiles at you, from its position on the wall on the right side of the screen. Once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at it to kill it...
...four Kamome will come flying towards you from behind; once you've moved out of their way and shot Black (or Green, or Orange, or Level-2, or Level-1) at each of them to kill them, you will come to three more Fire Flowers that are firing projectiles at you, from their positions on the wall on the right side of the screen. Once you've shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of these, to kill them, you will come to two more Fire Flowers (the thirty-ninth or thirty-sixth of which is flashing) that are firing projectiles at you from their positions on the wall on the right side of the screen - and once you have shot off Black (or Green, or Orange, or Level-2, or Level-1) flame at both of these, to kill them, the thirty-ninth (or thirty-sixth) one will send an eighth randomly-generated powerup flying towards Huey and Siria. Once you have collected it, it will for a seventh (or sixth) time take its effects on Huey (or Siria); you will then come up to a fortieth (or thirty-seventh) Fire Flower, that is firing projectiles at you, from its position upon that wall on the left side of the screen. Once you've shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at it, to kill it, you will come to two more Fire Flowers that are firing projectiles at you, from their positions on the wall on the right side of the screen - and once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at both of them to kill them, you will come to an eighth (or sixth) Iron Wall in the centre of the screen. Once you've shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at it to kill it, you'll come to two more Fire Flowers that are firing projectiles at you, from their positions on the wall on the left side of the screen; once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at both of them to kill them, you will come to a forty-fifth (or forty-first) Fire Flower that is flashing while firing projectiles at you from its position on that wall on the right side of the screen. Once you've shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at it to kill it, it will send a ninth randomly-generated powerup flying towards Huey and Siria - and once you have collected it, it will for an eighth (or seventh) time take its effects on Huey (or Siria). You will then come to three more Fire Flowers that are firing projectiles at you, from their positions on that wall on the left side of the screen; once you've shot Black (or Green, or Orange, or Level-2, or Level-1) flame at each of these, to kill them, you will come to a ninth (or seventh) Iron Wall in the centre of the screen. Once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at it to kill it, you will come to a forty-eighth (or forty-fourth) Fire Flower that is firing projectiles at you from its position on the wall on the left side of the screen - and once you have shot off Black (or Green, or Orange, or Level-2, or Level-1) flame at it to kill it, you will come to five more Fire Flowers (the fifty-first, or forty-seventh, of which is flashing), that are firing projectiles at you, from their positions on that wall on the right side of the screen. Once you've shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of these to kill them, the fifty-first (or forty-seventh) one will send a tenth randomly-generated powerup flying towards Huey and Siria; once you've collected it, it will for a ninth (or eighth) time take its effects on Huey (or Siria). You'll then come to a fifty-third (or fiftieth) Fire Flower that is firing projectiles at you, from its position upon the wall on the left side of the screen - and once you have shot off Black (or Green, or Orange, or Level-2, or Level-1) flame at it to kill it, you will come to a fifty-fourth (or fifty-first) Fire Flower that is firing projectiles at you, from its position on the wall on the right side of the screen. Once you've shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at it, to kill it, you'll come up to two more Iron Walls in the centre of the screen; once you've shot off a Black (or Green, or Orange, or Level-2, or Level-1) flame at both of them to kill them, two more Kamome will come flying towards you from behind. Once you have moved out of their way and shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at both of the two additional Kamome to kill them...
...three Tonbi will emerge from the ocean, then come flying towards you from behind; once you have moved out of their way and shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, two more Tonbi (the fourth of whom flashes) will emerge from the ocean, and come flying towards you from behind. Once you have moved out of their way, then shot off Black (or Green, or Orange, or Level-2, or Level-1) flame at both of them to kill them, the fourth one will send an eleventh randomly-generated powerup flying towards Huey and Siria - and once you have collected it, it will for a tenth (or ninth) time take its effect upon Huey (or Siria). Twenty more Tonbi (the eleventh of whom is flashing) will then emerge from the ocean, and come flying towards you from behind; once you have shot off a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, the eleventh one will send off twelfth randomly-generated powerup flying towards Huey and Siria. Once you have collected it, it will for an eleventh (or tenth) time take its effect on Huey (or Siria) - and five more Kamome (the fifth of whom is flashing), will then come flying towards you from behind. Once you've moved out of their way and shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at each of them, to kill them, the fifth one will send thirteenth randomly-generated powerup flying towards Huey and Siria; once you have collected it, it will for a twelfth (or eleventh) time take its effect upon Huey (or Siria). The main theme that you were hearing from the Yamaha YM-2151 will then change to a reprise of the first boss theme, as Huey and Siria come to Rock Head (but don't stop moving forward on account of it), who attacks by trying to stay ahead of them, while spitting four spreading rocks at them from his mouth (which cannot be destroyed) - and as with Magma Dragon, his whole body is the vulnerable point, which means that whenever Huey and Siria shoot a flame at him, it will count as a hit. However, once you have fired enough shots at him, he will split into nine separate parts and any rocks that are currently on the screen will explode; his central part (the one with his eyes) will then start flying directly towards Huey and Siria while his other eight parts start revolving around him in an anticlockwise direction. But once you have shot enough Black (or Green, or Orange, or Level-2, or Level-1) flames at his aforementioned central part to defeat him, he will explode, and Huey and Siria will proceed onto the sixth stage (which will return them to normal speed).
