The Portal turret plushie comes complete with a big glowing red eye and motion sensor – it will blurt out its oft rehearsed lines when anybody passes in front of it, and it even has context sensitive quotes it will say when being picked up or knocked over, or even when being ignored for 30 seconds (“Are you still there”), similar to the game counterpart.
The plushie will go on sale in mid-December for 30 American dollars over at ThinkGeek. You can opt in for an e-mail notification for when the item will be in stock by clicking the big button over there (saying EMAIL ME on it).
Unfortunately, these turrets do not include the dual machine guns that fire whole bullets, they are not filled with bullets, and only come in one color (white).
