Once Huey and Siria have reappeared at the bottom of the screen, they'll start moving forward again for a seventh time as the stage's main theme starts to be heard from the Yamaha YM-2151, and thirty Saucers come flying towards you from the top of the screen; once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, to kill them, four Eye Cannons will emerge from the ground on the left and right sides of the screen and fire projectiles at you. Once you have dropped a bomb upon each of them to kill them, five Shells (the third of whom is flashing) will come flying towards you from the top of the screen, while firing bubbles at you (which can be blocked for 20 extra points apiece). Once you have shot off Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, the third one will send a randomly-generated powerup flying towards Huey and Siria; once you've collected it, it will take its effects on Huey (or Siria). Four more Eye Cannons will then emerge from the ground and fire projectiles at you - and once you have dropped a bomb on each of these to kill them, you will come to an Orange Egg on the left side of the screen. Once you have dropped a bomb upon it, to destroy it, an orange orb with a claw print upon it will come flying out of it towards Huey and Siria; after you have collected it, Huey (or Siria) shall turn cyan as it takes its effects upon him. Four more Eye Cannons will then emerge from the ground and fire projectiles at you - and once you have dropped a bomb on each of these to kill them, sixteen Mini Flyers will come flying towards you from the left and right sides of the screen, while firing projectiles at you. Once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, four more Eye Cannons will emerge from the ground and fire projectiles at you; once you've dropped a bomb on each of them to kill them, ten more Saucers will come flying towards you, from the top of the screen. Once you've shot Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, four more Eye Cannons will emerge from the ground and fire projectiles at you - and once you have shot off Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them you will come to a Black Egg on the right side of the screen. Once you've dropped a bomb upon it to destroy it, a black orb with a lightning bolt on it will come flying out of it towards Huey and Siria; once you have collected it, it will take its effect on Huey (or Siria - and it will also turn them back to its colour if they'd collected the orange orb earlier). Eight more Eye Cannons will then emerge from the ground, and fire projectiles at you; once you have dropped a bomb on each of them to kill them, ten more Saucers will come flying towards you from the top of the screen. Once you have shot off a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of these to kill them, five more Shells will come flying towards you from the top of the screen while firing bubbles at you (which, again, can be blocked for 20 extra points apiece) - and once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) at each of them, to kill them, you will come to up another Orange Egg in the centre of the screen. Once you have dropped a bomb upon it to destroy it, a second orange orb with a claw print on it will come flying out of it towards Huey and Siria; once you have collected it, it will again take its effect upon Huey (or Siria - and it will also turn them back to its colour if they had collected that black orb earlier). Two Hotaru will then come crawling towards you upon the left and right sides of the screen while firing projectiles at you; once you have dropped a bomb upon both of them to kill them, you will come to a Saibou that is hovering up and down in the centre of the screen. Once you have shot off a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at it, it will explode, into four medium-sized versions of itself - and once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, they will explode into eight smaller versions of themselves. Once you've shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, they will disintegrate, and two more Hotaru will come crawling towards you on the left and right sides of the screen, while firing projectiles at you; once you have dropped a bomb on both of them to kill them, you will come up to another Saibou that is hovering up and down in the centre of the screen. Once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at it, it will explode, into four medium-sized versions of itself - and once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, they will explode into eight smaller versions of themselves. Once you have shot off a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of these, they'll disintegrate, and six more Hotaru will come crawling towards you on the left and right sides of the screen while firing projectiles at you; once you have dropped a bomb on each of them to kill these, you will come to a third Saibou that's hovering up and down in the centre of the screen. Once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at it, it will explode into four medium-sized versions of itself - and once you've shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, they will explode into eight smaller versions of themselves. Once you've shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, they will disintegrate and ten more Saucers (the fifty-fifth of which is flashing) will come flying towards you from the top of the screen; once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, the fifty-fifth 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) - and six more Hotaru will then come crawling towards you on the left and right sides of the screen, while firing projectiles at you. Once you have dropped a bomb upon each of them to kill them, an eleventh Shell will then come flying towards you from the top of the screen, while firing bubbles at you (which, once again, can be blocked, for 20 extra points apiece); once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at him, to kill him, you will come to a Blue Egg in the centre of the screen. Once you have dropped a bomb upon it to destroy it, a blue orb with a trident on it will come flying out of it towards Huey and Siria - and once you've collected it for the extra points, thirty Ghosts will materialize in front of you, and fly directly towards you. Once you've shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of these, to kill them, you will come to three more Saibou, that're hovering up and down in the centre of the screen; once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, they will explode into four medium-sized versions of themselves. Once you have shot off Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, they will explode into eight smaller versions of themselves - and once you have shot off Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, they'll disintegrate, and two more Shells will come flying towards you from the top of the screen, while firing bubbles at you (which, yet again, can be blocked for 20 extra points apiece). Once you've shot Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at both of them to kill them, Huey and Siria will stop moving forward for a sixth time, as Mijinko flies down into view from the top of the screen, then starts flying around in front of them while firing its own kind of bubbles at them (which, for a fifth time, can be blocked for 20 extra points apiece); however, once Huey and Siria have shot enough Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flames at Mijinko to defeat it, it will explode, and they will then start moving on forward again for an eighth time (but no further regular enemies will appear in the stage's remainder).
The main theme that you had been hearing from the Yamaha YM-2151 will then fade out, as Huey and Siria stop moving forward for a seventh time, and come to Dragon Zombie (who, like Magma Dragon and the Ice Dragons, is a different kind of dragon to Huey and Siria); the game's third boss theme will then start to be heard from the Yamaha YM-2151 for a second time as the background changes below Huey and Siria, and he starts flying around above them while spitting fiery flames at them from his mouth. His head is his only "vulnerable point", and while Huey and Siria are shooting their own Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flames at it to weaken him, he has the power to summon up an infinite amount of additional Ghosts to materialize in front of them, and fly directly towards them (which, much like the thirty you encountered before the background had changed, can be killed for 100 extra points apiece) - however, once Huey and Siria have managed to shoot enough of their own Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flames at his aforementioned head to defeat him, he'll explode, and they'll proceed to that eighth stage (which does not have a boss at all).
