User blog:Lightning the Skrill/Snow Wraith Frost?

so me and my friend at school were having this supid argument about logic in dragon breaths. Appearently, we moved from the Skrill to the Snow Wraith. Uhhh. But anyways, there are two things I want to ask.

1. What is the frost that this dragon fires?

Heres a picture of one option:



There is a projectile at the top. This seems far more logical, but definetly isn't a fusillade. As it is only one, explosive "frost?" projectile.

Another option:



This one sounds more obvious because it is a fusillade. But comparing the size of that thing, it seems far bigger than the snow Wraith's mouth. And plus, it looks like snow. And if it is the right one, what was the one before?

2. Second is how can the Snow Wraith, or any other ice dragon even survive?

First, dragons need body heat. Where does it get it from? Food? Carbon burning? If so, where does it get ice from? And it it has ice in its body, how would the food burn? And where does it get cold blasts from. Where does the Snow Wraith get its frost from?
