I feel your pain, as I understand it choosing your own avatar is an unlockable privilage that you can acquire in time. It will mean being a brocolli for a while yet but when the day comes that you can go back to being a pink chicken you will have that extra satisfaction associoated with a reward earned.
Otherwise Im glad to read you like the general feel.
