Please let my know if this is you.

Apperence:

Doe Horns
Skeleton Pelt
Real Deer Mask

This deer also was hanging out with Jala's deer and a grey pelted deer with the white horns and the skull mask.

The deer you met was my flighty Yeghig. Who ever this deer was, was able to get Yeghig's trust much more quickly then others.

*EDIT*

Also met a full zombie deer today at the pond with a little fawn. Thanks!
