The Mermaid and the Dragon.
A great thunderous roar shook The Lonely Mountain "AHH REVENGE! REVENGE! I SHALL SHOW YOU REVENGE!". Shouted Smaug one of the last great Dragons of Middle Earth to take his vengeance upon the men of Lake Town. He flew up into the air and fell back down again to shake the molten gold that the dwarves had tried to drown him in which in fact had only made him very angry (note to self after killing those filthy men and dwarves make a Gold Dragon Statuette). Then as he rose back into the air with his thunderous wings he proclaimed "I am Fire...I am Death" and with that he flew towards the men of Lake Town ready to wreak his vengeance.
Smaug felt a sick sort of glee as heard the townsfolk flee in terror from him once he burned this town to its very core, he would go about killing every last of those filthy little dwarves hiding in his mountain. He unleashed his fire upon the buildings and the lake shined and burned with his hellfire "Flee! Flee while you still can save yourselves from me!" he then made a dive at the lake picking up men and dropping them on blazing buildings, Smaug let out a twisted chuckle as he saw men women and children all trying to swim in the icy water just to escape his wrath.
Smaug then felt a very odd sensation hit his armor and noticed the bell tower there was a lone bowman who was challenging him. The great dragon had to admire this lone man even though he was a fool for standing up to him and would get eaten (Smaug was feeling a might peckish). This miserable human fired his last shot Smaug piped up "Oh that is not good running out of arrows when you have to slay a dragon,what are you going to do now..BOWMAN"? Smaug then noticed a smaller human standing with the bowman and he again inquired "Is that your son? You cannot save him, Bowman He will BURN!" As he slowly inched forward ready to make a meal out of these two foolish humans he heard something whisk into his chest.
The great dragon then felt a great pain in his chest he let a small burst of flame as this black arrow had pierced his very heart. Smaug was panicking and he flew up in the air flapping his wings in terror like an injured bird letting out a great bursts of flame and a cry of pain. Then as this great husk of body came barreling down toward the earth Smaug's lifeless corpse shook the very mountainside when it collided with the lake and its master. To the free peoples of Middle Earth Smaug the Great was dead...or so they thought.
Smaug's smelt a peculiar smell as he lay unconscious on a beach "By the Eldar what is that smell" he muttered as he finally awoke. It smelled like rotten fish and to his surprise he awoke on a beach with him smelling like said rotten fish. Everything was groggy his vision, his hearing, his speech and even his arms. ARMS? he thought to himself wait i have wings, not arms he looked down and saw that he had feet human feet and legs, at first he was confused then he looked down and yelped in terror. No this was some bad dream that is right a bad dream; he was still sleeping in his treasure horde after he ate all the humans, the dwarves and the filthy little barrel rider. Thinking very fast he remembered what his father Ancalagon told him "Son if you ever have a dream were you think you are human punch yourself in the face".
With this great piece of advice Smaug punched himself in the face and instead of waking up it ended up knocking him on the sand right on his butt. He reached for the sky and shouted "NO! anything but this i dont want to be a human, I was a king once, now I'm a filthy little human please let me rule the Lonely Mountain" He then heard a giggle coming from the water Smaug would not take this anymore he would destroy this giggle and its owner. Hiding behind a huge rock and laughing at this funny human was Ariel a little mermaid
"Who are you and why do you laugh at me?"
"I'm Ariel, I'm laughing at you because you are the funniest human i have ever seen. Also what is a Lonely Mountain?"
" I am no human you, I am a Dragon and i will eat you!" with that Smaug still not believing he was a human let out of his chest a big gasp of air instead of his trademark fire breath and he continued until he was out of breath. This caused Ariel to burst with laughter and Smaug would have no more of it so he charged into the water now this spooked Ariel to jump from her rock, she then charged him and whacked him with her tail. Smaug was knocked back onto the beach and he looked at her in shock for there before him was Girl with piercing blue eyes, fair pale skin, hair the color of flame, however instead of legs their was a huge emerald tail coming out of the water. Upon seeing this Smaug the Chiefest and Greatest of Calamities fainted!
