The somewhat dull yet amazingly smart and science driven squirrel girl we all love and know: Scarlet.
From the web-comic: "Sequential Art".

Fan-art. I don't own Scarlet as she is the property of the one and only JollyJack. AKA: Philip Jackson.
The hilarious bastard that he is.

His site is: "Collected Curios". All of his tame web-comics are hosted there.
