First of all don't apologise for trying to speak in a language that isn't your native. The fact you have learnt another language and are attempting to communicate in it is nothing at all to apologise about. Be proud of yourself for knowing enough of a new language to get your point across.
Secondly, I think I read somewhere that Frontier aren't interested in doing mythical, legendary or imaginary creatures. I cannot find the quote so I could be wrong but I'm 90% certain.
