Its a Hearthstone
Uhm, okay.
I don't know whats its from I just know its a really tasty treat ^v^
It's actually not a treat at all. In fact, if you tried to eat one, you'd probably break your teeth, because, as the name implies, it's a stone. It's an item from World of Warcraft. 
ohh... lol i dont really play World of Warcraft... but I thought it was a treat because in this picture its next to a bunch of food XD
Understandable! Rather odd placement, really. XD
Yes XD
