Cute nightmare

Five seconds later:
 

Once again, Spike gets all the mares.  
on another note,  
Today on Pony Planet, we have a rare case of this symbiosis at play. This fascinating creature is raising a young dragon named Nightmare Dragon Spike. One day or perhaps night, he will be at the beck and call of his dotting mare, razing villages, kingdoms, countries that threaten her with an army of other liked minded ponies and creatures at her will. And on very rare bloody moon, a frenzy feast at her calling. But until then, this little dragon is at the mercy of his surroundings and it’s up to this mare to teach and love the youngling.
