Why does Google not believe in unicorns??

Today I was reading Lifehacker, as all savvy internet bloggers such as myself are wanton to do!!  The article Search Google Images by drawing what you’re looking for shows us the web app GOOGLE IMAGE SEARCH BY DRAWING.

You draw a simple picture, and then the app searches Google Images for similar drawings!  I knew immediately that I HAD to test it out.

And what better image to search with than with a self-portrait of a handsome unicorn?  I drew my image and began my search:

What is Google trying to say with these bizarre and shocking results?  Where are the unicorns?? Does Google not believe in unicorns???  Is Google systematically erasing all traces of unicorns from the Web?!?!?

Is Google attempting to exterminate the entire unicorn race, and with it remove all hope, joy, love, and magic from the universe?

I of course do not offer any slanderous opinions here, I merely ask the questions that others dare not ask.
