When looking at a creatu, be it in the directory or your own pets. Do you imagine what sound they'd make for their species? Sometimes I do, but only a few of them at best. I'd always imagine Zaphaos having a light tone set of sounds with a few deep ones thrown in, I'd imagine Veram having fox-like sounds considering they look like them in a form, Zenirix I'd imagine would have dog-like sounds basing on it's look or maybe a wolf sound etc.

Just some thoughts, what are your ideas?
