Last year I has a discussion with a friend - she said me that all dragons should be pink under all those scales, fur or feathers.
But I disagreed saying her, that there are no such thing as pink dragons. you can get a pink one only if you catch a transparent crystal one - and I drew this image to illiustrate my idea.

Only after a while I understood that the dragon has no organs inside it. So if somebody asks - it's a spirit dragon, now ^..~
