Liked Balloonicorn so much in the Pyromania Update that you'd like to take him home with you? Because Balloonicorn could really use a place to crash at for a bit (one, two weeks max), he's going through a bit of a rough patch right now. Also, you totally won't even know he's there. Hey, look, also, could you pick Balloonicorn up some smokes on the way home? He's good for it, he's just waiting to get some money wired to him. Available through ThinkGeek and the Valve Store.
