Caribou?

I saw this pet the other day but i was so shocked i forgot to take a screenshot, is this possibly a pet? It said Caribou (which are deer) yet they ran off real fast, they definately were not White Moas, it clearly said in green caribou

Yup, you can't tame them, sorry to say.

Not tameable? That is to date my greatest sorrow concerning GW (next to Paragons not having real wings and Jora not getting her bear form). Having a caribou as a companion would be worth battling through three campaigns, throwing down evil in any shape or form whether undead, semi-dead or the gods themselves! Then just to be sure I had proved my worth, I would then trudge through one last journey to some distant outpost to send molten beasties to their graves!

The gods are terrible teasers!

hehe yea I tried at least 30 times with Zhed. lol I so wanted my Centaur to have a 4 legged caribou mate to run along with. lol I know I know I know I'm a sick sick man. lol
