If you want to link Penguin-Breeder.org from your site (and who wouldn't want to?), I have prepared a small icon you can use for the link or for otherwise refering to the Penguin-Breeder.org website.
You will find the icon in the links section. It resembles the new Penguin-Breeder.org layout.
Of course you don't have to use this icon. However, you are not allowed to modify it or use it for something not related to the Penguin-Breeder.org website.
