There is more Halloween fun to be had on Google aside from the HauntedHouse doodle. If you haven't noticed them already, Google really want you to notice their freebase results which makes the search engine a bit more like Wolfram Alpha and Siri.
Today a Google Doodle celebrates Halloween with an interactive logo on the search engine's homepage. Clicking on various features in the Doodle causes the image to come to life, complete with a spooky soundtrack.
One of Halloween's favorite traditions is the HauntedHouse and if you need help finding ones in your area, MapQuest has come to the rescue. They've teamed up with HauntWorld to provide a HauntedHouse search.
