My favorite February MC would have to be '06's Chyaku Norisu Scarf. It has a lot of very unique poses that go well with a variety of different outfits one can put on an avatar, and the bright red color means it won't just blend into those outfits to become a pixelated mess. No other scarf on Gaia has such a dramatic wave in the fabric - your avatar truly looks like a hero when wearing it.
Well Fudge, tough call.
I'd have to say the Zony.
First of all, the name has a close relation to Sony (Which is a good brand of MP3, and computer), I enjoy the detail put into it as well, and also I enjoy the fact it's one of those things to which I don't see many people with. It's a rare and expensive find.
