Parasite Dragon

In various pictures I have scribbled dragons that were being killed from the inside as tentacles sprouted out of their sides and mouths. I came up with the tentacles being a parasite that kills dragons, but then there was the question: Where do they come from?? So one day I drew this dragon and discovered that he was the ultimate dragon to be placed as the creator of the parasites. What he does is clamp his teeth into another dragon and then basically barf up the tiny parasite cell into the wound of the other dragon. After a time the cell will grow and eventually break itself out of the infected dragon. I pictured this dragon as a dark shade of blue and then purplish-red for the skin around his eye. He lives near gysers where everything is hot and misty. Don't ask my why there is a willow tree, that's the first thing I drew. XD Yes, the dragon is going to swallow that porcupine. The inside of his neck has a billion needles. Ha ha ha. I might color this one someday... Enjoy!
