StarCraft is invading World of WarCraft -- sort of. Blizzard has revealed the free pet that will be given to lucky Blizzcon attendees, and it looks like a long lost member of Jim Raynor"s space marines (via MMO Champion).

The pet is named Grunty the Murloc Marine, and it sports a wicked-looking gauss rifle. It will be available to anyone who attends BlizzCon 2009, or orders the DirectTV broadcast of the event. Last year"s gift was a polar bear mount.
