Penguins reek of herring!
Please, no penguins. I can think of a lot nicer animals to have as a
mascot. How about a ferret? They are much cuter, and nicer. Please,
anything but penguins.
Someone mentioned that it would be cool to have a mascot drawn in the
'japanese animation' style. And I fully agree. With that in mind, visit
the pages of a very talented Japanese artist:

I will see if I can get her to draw a mascot for Linux.
