Available only to players on realms located in North America, Europe, and Korea.
Players who purchase it receive a code similar to that of the loot cards. When you enter the code in your account all characters are mailed a copy of this pet, as well as any future characters you create.
It will randomly speak some of its larger counterpart's lines. This initially played for all nearby players, but was quickly hotfixed to play only for the pet's owner.
Hotfix (2009-04-19): "A hotfix was recently applied, which temporarily disabled some of the sounds Lil’ XT makes. The issue was that some of his sounds were flagged in such a way that they play for everyone around him and not just the player that owns the pet, an annoying problem to be sure. We can’t alter volume or who the sounds play for through a hotfix so the temporary workaround is to disable them completely right now until the proper fix can be patched in later."
