Hello NephraTari.
We here at
Cryptozoology and Mythical Beasts sure do receive a lot of first hand witness accounts of unknown beasts. We've had giant glowing
cats, small grinning gremlins, and werewolves with spikes growing out of their backs, but this is probably the strangest account I've heard.

Seriously.
If you're interested, I can do a sketch of your creature based on your own in-depth description. You've already described the basic texture of its
skin and shape of the body, all i need are the following:
- colour (any colour patterns?)
- size (width, girth, length)
- facial features (if it wasn't going too fast to see)
- any strange appendages
(u2u me or post the description here)
Kudos to your experience, NephraTari. Very few people get the chance to witness something supernatural or mystical.
