Of the faction pets, this was the hardest to get as Halpa is well hidden behind some tents. This lend credence that there ARE Tauren Rogues, but they're just so good that we can't see them.

The spinning he does almost seems like a dance to me. For an undead whelpling, he seems quite cheery--as though being an undead frost wyrm doesn't mean you can't have a warm heart!

The Bogflare Needlers drop Unidentifiable Plant Parts as well, which you can use to hand in for Cenarion Expedition for a RR quest. (However, that quest only lasts until Honored. Once Revered, you can no longer hand them in.) Sadly, you cannot skin them, unlike silithids.

You must be patient with this one. Unlike the other Whelps, these seem the hardest to find. As you may notice, the mobs that drop 'em are the lowest leveled. As Alliance, this will be easier to get, but as Horde, the best route to get to them is to fly to Arathi and run down to the Wetlands.

Overall, they are the most annoying (as Horde) to farm because of the low worth on the leathers and hides. For me, it took me about 5 days to farm, so don't get discouraged and good luck!

Of the whelps, I found this the second easiest to farm. I'm on a small server, so I don't need to worry about people popping for a 'quick farm' when they pass the spot on the side of the road. (Of the hardest, I'm finding the Dark Whelpling the worst. It took me 3 days for that one! Although it really is just chance :P) Besides, they're in a circle, for easier farming!

As Darias mentioned, the Badlands (Lethlor Ravine) is the easiest place. Also, if you have mining, there's some gold and diamond nodes there. While I was farming these Whelplings, people would run through to to the mining nodes, leaving the Whelplings for me.
The problem Dustwallow Marsh is that they are so spread apart that it makes them very cumbersome to find.

There are many places to farm for this, and some good reasons for each place. I primarily farmed in Un'Goro and Felwood. There's a nice circular route you can use in Felwood, as well as the possibility to find the rare ooze mob that has the highest drop rate of them all. I also farmed in Un'Goro because there you can get soil to either use for the Morrowgrain reputation repeatables for Thunder Bluff or to sell on the AH. This was fun to farm because of the bags that you get to open!

I started with this as my first Whelpling to farm and WOW, is it easy! I originally attempted at the Dark Whelpling, but I was getting nowhere and I really wanted the Azure one. Even if someone else is farming with you, you still have a great chance to get it. There's enough mobs with a fast enough spawn rate, that if you head either a little more south (or north), you won't bother them and still have a very good chance at it yourself!
