It's not really a secret at all, I've been very much addicting to hopping around the grid in my petite avatar from Fallen Gods. I don't think I'm the only one that's caught the petite madness either. De La Soul has shrunk down their Archer tunic to fit these pint-sized mesh avatars, and for those with have a taste for the medieval, these tunics are great for accomplishing that look on a bite sized you.
