After Astrid's Nadder had blasted a powerful fireball on the giant dragon, Hiccup had watched the dragon closely. He turned toward Ruff and Tuff and saw them messing about on their twin headed dragon. He shook his head quickly before he shouted out with all of his lungs. "Ruff! Tuff! Do you want your parents to make it out of this alive!" he shouted out loud.
They both immediately stopped, and turned to him surprised that this was the first time they have heard him talk. Not only was this the first time that they noticed him talk, but also the first time he had expressed annoyance with a shout. When they both came to they nodded slowly at Hiccup.
Hiccup gave a slow nod before he turned toward the battlefield. When he looked at the dragon he noticed that he did not know anything about it. So he turned to the expert known as Fishlegs.
"Fishlegs! Think you can break that dragon down for me?" he asked. Fishlegs gulped as he nodded and turned toward the dragon to begin breaking down any flaw that this dragon might have. Hiccup listened closely to everything Fishlegs had told him while watching the dragons each and every detail. He saw what Fishlegs was talking about. Hiccup turned to the others and told them, "Alright, right now I want all of you to find a weakness. If you can't I want you to try to hit him with every ounce of power your dragon can muster," he said. Every one of them nodded to him before turning their dragons to charge into the battle.
Hiccup turned back to Astrid and said, "let's go... we have to find Toothless, and quick." They flew slowly and looked at each and every ship and found the Figure of Hiccup's brother Toothless still bound to the ship. Hiccup pointed down and told Astrid, "There he is. Take me down there." Astrid nodded and led her Deadly Nadder over the ship. Hiccup surprised her when she felt that he was no longer behind her. Astrid Turned looked down and saw that Hiccup had jumped off of her Nadder before she could even land.
Before she could do anything else Hiccup screamed out to her, "Go Astrid! Go help the others!" Once the message was out Hiccup turned back around to run to his brother. She was worried at this point and asked, "what about you hiccup?" He stopped in his tracks and quickly turned to her. "Don't worry about me Astrid! Just go help them out! I'll be okay!" he screamed before continuing toward Toothless.
Astrid looked toward his retreating form for a few seconds. In her mind she knew that she should trust him, but inside of her heart she felt that something would happen to Hiccup if she wasn't there. However she remembered that she needed to trust that Hiccup would be okay. So begrudgingly she made the Nadder turn around and charge in to help the others battle the Giant beast.
Hiccup arrived with Toothless and quickly removed the leather strap that had covered his mouth. At first he tried to remove the rest by tugging at the chain but then remembered one thing. His glove could probably melt it. He turned toward Toothless, extended his hand out, and said, "alright bud blast my arm... quickly!" he said. Toothless complied and shot a small fireball toward Hiccup's hand. Once the glove was lit Hiccup grabbed the chain and tugged with all of his strength. The fire had luckily been strong enough to start melting the chain for where he had grasped it. Tugging harder and harder he felt the chain begin to weaken. With one final tug he broke the chain. Once the chain was broken Toothless overpowered the other chain with a mighty tug that ripped it off of the wooden floor.
Hiccup now got to work on the wood surrounding his friend's head. He grabbed at the metal parts of the wood and managed to melt it off of its hinges as the circular wooden piece fell to the floor. Hiccup smiled when his friend spread his wings to celebrate his freedom. Both were too happy to notice the Giant dragon stomp its food near the other boats. The shockwave of the impact sent Hiccup flying far away from Toothless. His body hit the ground a couple of times before coming to a complete stop against a large rock.
