Once Huey and Siria have reappeared at the bottom of the screen, they will start moving forward again for a sixth time as the stage's main theme starts to be heard from the Yamaha YM-2151 and sixteen Tombows come zigzagging towards you on left and right sides 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, two Hedgehogs will emerge from the ground and jump into the air while firing their spikes at you. 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 the spike-covered wall on the right side of the screen (which will count as an instant death if you fly into it) will extend and the other spike-covered wall on the left side of the screen (which will also count as an instant death if you fly into it) will recede as two more Hedgehogs emerge from the ground and jump into the air, while firing their spikes at you - and once you have shot a Black (or Green, or Orange, or Level-2, or Level-1) flame at both of these to kill them, the spike-covered wall upon the right side of the screen will extend for a second time and the other spike-covered wall on the left side of the screen will recede for a second time, as six more Hedgehogs emerge from the ground and jump into the air while firing their spikes at you. 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 spike-covered wall upon the left side of the screen will extend and the other spike-covered wall upon the right side of the screen will recede, as ten Ice Butterflies come flying towards you from the top 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, two more Hedgehogs will emerge from the ground and jump into the air while firing their spikes at you. Once you have shot off Black (or Green, or Orange, or Level-2, or Level-1) flame at both of them to kill them, you will come to a Silver Egg in the centre of the screen - and once you have dropped a bomb upon it to destroy it, a silver orb with a crescent moon on it will come flying out of it towards Huey and Siria. Once you've collected it, Huey (or Siria) will turn silver as it takes its effect on him.
Four more Hedgehogs will then emerge from the ground and jump up into the air, while firing their spikes 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, you will come to an Orange Egg upon the right side of the screen. Once you've dropped a bomb on it to destroy it, an orange orb which has a claw print on it will come flying out of it towards Huey and Siria - and once you've collected it, it will take its effect on Huey (or Siria; it will also turn them back to its colour if they had collected that silver orb earlier). Four Ice Turtles will then come walking towards you in the centre of the screen, while firing icicles at you - and once you've dropped enough bombs on each of these, to kill them, three more Hedgehogs will emerge from the ground and jump into the air while firing their spikes at you. Once you've shot off Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of these three to kill them, ten more Ice Butterflies 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 them to kill them an enormous icicle will emerge from the spike-covered wall upon right side of the screen. Once you've shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1), flame at it to make it recede four more Ice Turtles will come walking towards you in the centre of the screen, while firing icicles at you - and once you've dropped enough bombs on each of these, to kill them, both of the spike-covered walls on the left and right sides of the screen will extend for a third and second time, as fifty more Ice Butterflies 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 these, to kill them, two more enormous icicles will emerge from both of the spike-covered walls on the left and right sides of the screen; once you've shot off Silver (or Black, or Green, or Orange, or Level-2, or Level-1) at both of these, to make them recede, both of the spike-covered walls upon the left and right sides of the screen will recede for second (and third) time as three more Hedgehogs emerge from the ground and jump into the air while firing their spikes at you. Once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of these to kill them, three Babito will come flying towards you from behind while firing frozen curves from their tails at you - and once you have moved out of their way and shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, ten more Ice Butterflies (the 80th of whom is flashing) will come flying towards you from the top of the screen. 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 the 80th one will send a randomly-generated powerup flying towards Huey and Siria; once you've collected it, it will take its effect upon Huey (or Siria). Sixty-four more Tombows will then come zigzagging towards you on the left and right sides of the screen - and 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 spike-covered wall on the right side of the screen will extend for a fourth time, and the other spike-covered wall on the left side of the screen will recede for fourth time, as two more Ice Turtles come walking towards you on the left side of the screen, while firing icicles at you. Once you have dropped enough bombs on both of them to kill them, twenty more Ice Butterflies (the 90th of whom is flashing) will come flying towards you from the top of the screen; 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, the 90th one will send another randomly-generated powerup flying towards Huey and Siria. Once you've collected it, it will again take its effect on Huey (or Siria) - and the spike-covered wall on the right side of the screen will then extend for a fifth time as two more Ice Turtles come walking up towards you in the centre of the screen while firing icicles at you. Once you have dropped enough bombs upon both of these to kill them, twenty more Ice Butterflies (the 110th of whom is flashing), 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 them to kill them, the 110th one will send a third randomly-generated powerup flying towards Huey and Siria. Once you've collected it, it will once again take its effect on Huey (or Siria) - and that spike-covered wall on the left side of the screen will then extend for a sixth time, and the other spike-covered wall on the right side of the screen will recede for a fifth time as twenty more Ice Butterflies (the 130th of whom is flashing) come flying towards you, from the top of the screen. Once you've shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, the 130th one will send a fourth randomly-generated powerup flying towards Huey and Siria; once you have collected it, it will yet again take its effects on Huey (or Siria). A group of thirty-two more Tombows will then come zigzagging towards you, on that left side of the screen - and once you have shot off a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them, to kill them, a fourth enormous icicle will emerge from that spike-covered wall on the left side of the screen. Once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at this to make it recede, thirty-two more Tombows will come zigzagging towards you on the left side of the screen; 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, two Ice Dragons (who, much like Magma Dragon, are different kinds of dragons to Huey and Siria) will materialize in front of you and spit an icy flame at you. Once you have shot off one of your own Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at both of them to kill them, they will explode into three pieces of shrapnel (which can be blocked for 20 extra points apiece) - and a fifth enormous icicle will then emerge from the spike-covered wall on the right side of the screen. Once you've shot off Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at it to make it recede, the spike-covered wall on the left side of the screen will extend for a seventh time as a sixth enormous icicle emerges from it, and that other spike-covered wall on the right side of the screen will recede for a sixth time; once you have shot off a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at the sixth enormous icicle to make it recede, sixteen more Tombows (the 159th of whom is flashing) will come zigzagging towards you upon the left and right sides 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 159th one will send a fifth randomly-generated powerup flying towards Huey and Siria - and once you have collected it, it will for a fifth time take its effects on Huey (or Siria). The spike-covered wall upon the right side of the screen will then extend for a sixth time and the other spike-covered wall on the left side of the screen will recede for a fifth time, as three more Ice Dragons materialize in front of you and spit an icy flame at you; once you've shot off one of your own Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them they will explode into three pieces of shrapnel (which can, again, be blocked for 20 extra points apiece). You will then come to a Black Egg in the centre of the screen - and once you have dropped a bomb on 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 effects on Huey (or Siria; it will also turn them back to its colour if they'd collected the silver or orange orbs earlier but its charged shot is more effective against enemies).
Sixteen Mini Flyers will then come flying towards you on the left and right sides of the screen while firing projectiles at you; once you've shot off Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, six more Ice Dragons will materialize in front of you, and spit an icy flame at you. Once you've shot off one of your own Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flames at each of them to kill them, they will explode into three pieces of shrapnel (which can, once again, be blocked for 20 extra point apiece) - and a seventh enormous icicle will then emerge from the spike-covered wall on the right side of the screen. Once you've shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at it to make it recede, ten more Ice Butterflies will come flying towards you, from the top of the screen - and once you have 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 up to a second Orange Egg in the centre of the screen. Once you have dropped a bomb on it to destroy it, another 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 take its effects on Huey (or Siria - and it will also turn them back to its colour if they'd collected the silver or black orbs earlier). A twelfth Ice Dragon will then materialize in front of you and spit an icy flame at you; once you have shot one of your own Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flames at this one to kill him, he will explode into three pieces of shrapnel (which can yet again be blocked for 20 extra points apiece). The spike-covered wall on the left side of the screen will then extend for an eighth time, as two more Hedgehogs emerge from the ground and jump up into the air while firing their spikes at you - and once you have shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at both of them to kill them, a thirteenth Ice Dragon will materialize in front of you, and spit an icy flame at you. Once you have shot off one of your own Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flames at this one, to kill him, he will explode into three pieces of shrapnel (which can, for the fifth time, be blocked for 20 extra points apiece); the spike-covered wall upon the right side of the screen will then extend for a sixth time, and the other spike-covered wall on the left side of the screen will recede for a sixth time, as twenty more Ice Butterflies (the 160th of whom is flashing), 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 these to kill them, the 160th one will send a sixth randomly-generated powerup flying towards Huey and Siria - and once you have collected it, it will for a sixth time take its effect on Huey (or Siria). Two more Hedgehogs will then emerge from the ground and jump up into the air, while firing their spikes at you; once you've shot off Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at both of them to kill them, two more Ice Dragons will materialize in front of you and spit an icy flame at you. Once you have shot one of your own Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flames at both of these two, to kill them, they will explode into three more pieces of shrapnel (which can, for a sixth time, be blocked for 20 extra points apiece) - and that spike-covered wall upon the left side of the screen will then extend for a ninth time, as you come to a Blue Egg on the right side of the screen - and once you have dropped a bomb on it to destroy it, a blue orb with a trident on it will come flying out of it towards Huey and Siria. Once you have collected it (for the extra points), two more Ice Turtles will come walking towards you on the right side of the screen while firing icicles at you; once you've dropped enough bombs upon both of them to kill them, the spike-covered wall on the right side of the screen will recede for seventh time as twenty more Ice Butterflies (the 180th of whom is flashing) 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 180th one will send a seventh randomly-generated powerup flying towards Huey and Siria - and once you have collected this, it will for a seventh time take its effects on Huey (or Siria). Two more Ice Dragons will then materialize in front of you, and spit an icy flame at you; once you've shot off one of your own Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at both of these to kill them, they will explode into three more pieces of shrapnel (which can, for a seventh time, be blocked for 20 extra points apiece). Both of the spikecovered walls on the left and right sides of the screen will then extend for a ninth and sixth time as seven more Hedgehogs emerge from the ground and jump into the air while firing their spikes at you - and once you've shot a Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flame at each of them to kill them, three more Ice Turtles will come walking towards you in the centre of the screen while firing icicles at you. Once you have dropped enough bombs upon each of them to kill them, both of the spike-covered walls on the left and right sides of the screen will recede for a seventh and eighth time, as ten more Ice Butterflies come flying towards you, from the top of the screen; 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, eight more Ice Dragons will materialize in front of you and spit an icy flame at you. Once you've shot off one of your own Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flames at each of them to kill them, they will explode into three more pieces of shrapnel (which can, for an eighth time, be blocked for 20 extra points apiece) - and the main theme that you had been hearing from the Yamaha YM-2151 will then fade out, as the two spike-covered walls on the left and right sides of the screen scroll out of view (no more instant deaths), and Huey and Siria stop moving forward for the fifth time in the game.
The game's second "boss" theme will then start to be heard from the Yamaha YM-2151 for a second time as Ice Worm emerges from the first hole in the wall on the left side of the screen, and starts spitting icicles at you from his mouth; much like Magma Dragon (and Rock Head before he split up into nine parts), his entire body is his vulnerable point, which means that whenever Huey and Siria shoot a flame at him, it will count as a hit. However, he has this power to disappear into one of the five other holes in the walls on the left and right sides of the screen (so that you cannot attack him any further), before re-emerging from another one of them at random - but once Huey and Siria have shot enough Silver (or Black, or Green, or Orange, or Level-2, or Level-1) flames at him to defeat him, his body (like Magma Dragon's) will explode into ten sections, and the two dragons will proceed on to that seventh stage.
