Looking to build toward 150 toys for the Toymaster achievement? There's an easily obtainable toy in Townlong Steppes, but it's quite hidden, and also ... kind of disturbing.
In the caves beneath Niuzao Temple lurks an ancient watcher, apparently from the same Titan brand as Archavon. His name is Huggalon the Heart Watcher. He looks just like the Wrath-era raid boss, if you ignore the giant purple bow on his head. And you should.
To find him, enter the caves on the west side of the island. Take the first right and follow the right-hand walls. Just before you pass through an entrance lit by glowing beetles, you'll see a small passage up and to the right. At the end of this passage, Huggalon waits. You won't see a rare icon on your map because he is not a rare spawn.
He's easily soloable in Siege of Orgrimmar gear, but feel free to bring friends if you might need backup. He does hit hard against cloth and has a decent chunk of health. Or, you can give this lonely giant the hug he yearns for and walk away.
If you opt for murder, you'll be rewarded with the B.F.F. Necklace. You can place it in your toybox and then choose a player to be Friends Forever! with once per day. But honestly, who wants to be friends with a cold-blooded killer like you?
While you're in the cave, keep an eye out for Fragment of Dread, part of the Riches of Pandaria achievement.
