This battle pet is from the "War of the Elements." TCG set.  The code for it must be redeemed on WoW's Promotion page which gives you an in game code for "Landro Longshot" an npc in booty bay.  

This pet has a unique sound file for it's laugh when it kills an enemy in battle. It also has the ability to randomly ice block nearby critters and frostbolt them to death.  The card does unfortunatly share the same skin as the blizzard store lil'kt pet.

The flavor text on the card is "How the goblin Landro Longshot initially came into possession of the lichling remains a mystery, but he was all too eager to wager it in a game of cards."
