removing header graphic on childreness theme

I want to replace the panda above the menu bar on the Childreness theme. I can't find this graphic in my files, nor I can't find a reference to it anywhere in the code, either. Where is that darn panda?!

Never mind, sorry. I have a new computer and the thumbnail previews on my new art software showed the menu pngs in a different way. Didn't see the panda there, but he's gone now.
