This pet does NOT spawn a rare version in the wild. You must use a stone. Don't waste your time farming. I am fairly certain that the blue skin is unique. Grab one, stone it, and happy days :)

Got him! Your account level on HOTS goes up when your character goes up. It costs 100k XP to go up from level 1 to 2. Your best bet is to level up 20 heroes from level 1 to 2 = 20 matches. Matches lasted on average 15 minutes for me. I recommend going against AI with human team mates (not AI ones, gawd they are awful) and don't go near the PVP areas. 

I found these guys after midnight, server time (29 December 2019). Thanks to Deekore's post I was able to get through the green Fel Barrier by letting the mobs kill me & rezzing on the other side. Tip - die near the barrier that's covering the hole (not the wall) as that gets you through to a ledge and after you check that area you can drop to the rest of that area. There are 2 cellar entrances.
