Kiko - Rock! View all Avatars

Go to the Music page. Open Source (right click on the white background, view source - if this doesnt work for you then I suggest that you clear your temporary internet files and restart your computer), press CTRL F and search for the word secret. You will see an URL. It will look like this (not exactely the same, its different for everyone):

http://www.neopets.com/music.phtml?
secretavatar=89c6b7767dd9516642a6d63768e9329d

Copy the whole url, paste it in your adress bar and press enter.
