Shortly after the release of World of Warcraft's second and record-breaking expansion World of Warcraft is celebrating its 4-year anniversary today with its 11 million subscribers. Players will not only complete an in game achievement when they log on, but will also receive a special Baby Blizzard Bear vanity pet. This cute little companion pet also utilizes a feature new to Wrath of the Lich King the 'bind on account' ability. Normally most items used by your character become soulbound (unable to transfer the item to other characters.) Being bind on account allows you to send this pet to every character on your account regardless of when they were created.
