Help Finding a Void Worm pet?

[Bulletdance]

Hi. haven't been on here in a while, but started playing WoW again and saw a hunter with a cool worm pet I'd like to tame. I can't find it in the pet section of this site. It was a worm, but one of the models where it pops out of the ground and you only see half of it. It was purple and voidy with white glowy whiskers. Anyone know how I can tame it? I saw it on an alliance char, but couldn't grab a screen shot.

It may have been some kind of legacy tame, where a creature that wasn't meant to be tameable was for a short time. But I'm not sure.

If you're talking about the worm that has the skin kinda like https://www.wowhead.com/npc=224580/bloodcrust-behemoth, It was a short time tame. They are not available anymore. The people who got them got to keep them. They do that sometimes unless it's a baby pet.
