Who doesn't love penguins? Well, definitely not us over here at WoW Insider. During one Insider show, we clamored for penguins to be the special pet to be included in the Wrath of the Lich King Collector's Edition. We know they haven't even announced a Collector's Edition yet, but since they've released one for most of their games -- they did it for both World of Warcraft and The Burning Crusade -- there's a good chance they'll be announcing one soon.

At any rate, fans of birds in tuxedos should rejoice. Tipster Josh led us to a collation of images (um, caveat clickor, as they say in Latin) that were apparently data-mined from the Wrath of the Lich King Alpha client. In it, we saw some blue dragonkin presumably from the Nexus using the same models with slightly different armor (ho-hum); some Undead versions of the Nerubians (Stratholme, anyone?) and the oversized Vrykul (interesting...); first looks at the Alliance and Horde siege machines (I want TOYS!); and -- you guessed it -- penguin pets (wahoo!). We have no idea how players will be able to get them, or even if they're obtainable as pets, but the spark of hope for pet lovers everywhere remains aflicker!
