Now I Know These Characters
 

I finally knew who this blue monster really is and his name is Sapphire. I drew Sapphire many times before, especially in July 2010, when I'm at my peak of my obsession with Foster's Home for Imaginary Friends, and Sapphire was formerly Keystone Blop. And as for Ruby, this is the first time on DeviantArt for Ruby. Ruby is just a first-timer. Now you possibly know who they are.

P.S. should there really be a Gallery of Friends in the Season 3 DVD?
