That's why we'd like to inform you of the latest Avatar Marketplace update, a cheaper alternative for your fixation with dress-up. Two new game styles are available: A World of Keflings and Army of Two. You can find a plethora of branded hats and shirts from each title, as well as some full body costumes -- you can see the Ninja Bee outfit above.
