It's just a mascot! She doesn't exist... However if you have aother ideas, why don't you show it? ;-)
I think I'd choose an Ant as superficially an Ant seems tiny, inconsequential .. but can lift weights many times its size!
One must be careful, politically, with the female images. How about a fox. Carl had a picture of one at his house. I do think an ant is appropriate, but I myself don't like bugs. We have the penguin. We have the Gnu. Animals seem to be the popular way to go. I wonder if a really appropriate mascot might be the Javan rhinoceros, because there are only about 50 of them in the world.
