We're pleased to announce that the two recently revealed in-game pets, Lil' Ragnaros and the Moonkin Hatchling, have now made their way to the Pet Store section of the online Blizzard Store at a price of $10 each.

Like last year's Pandaren Monk, the Moonkin Hatchling has a soft spot for helping children. For every Moonkin Hatchling adopted from now through December 31, 2010, Blizzard Entertainment will donate 50% of the $10 purchase price to the Make-A-Wish Foundation®.

Thanks to the support of all the World of Warcraft players out there who purchased the Pandaren Monk last year, we were able to donate more than $1.1 million to the Make-A-Wish Foundation this past February. We're looking forward to making another big contribution to this great cause on behalf of the World of Warcraft community following the close of this year's promotion.

To learn more about the Pet Store, please visit the Pet Store FAQ, and for more information about the Make-A-Wish Foundation in the U.S. visit www.wish.org and outside the U.S. visit www.worldwish.org.

Just in time for the holiday season, SteelSeries is releasing the first in a series of Diablo III mouse pads. The QcK Barbarian Edition features artwork from the game, showcasing the might and fury of the barbarian. For more information visit SteelSeries at http://steelseries.com/diablo3.
