Happy Halloween everyone! Here are the logos from Google, Yahoo, Bing, Ask, Dogpile and others. For the past year's special Halloween logos, see the 2009, 2008, 2007, 2006, 2005 and 2004 Halloween logos.
This year, Google has a very special Halloween logo featuring the Scooby-Doo cartoon. You can flip between the five different logos by clicking on the right arrow, clicking on the logo or clicking on the palm imprint under the logo. For those who follow the forums, you want to see the special Google forum trick. :)
Here is a short video showing off the logo:
