Today, Google celebrates Halloween with an awesome stop-motion Halloween witch doodle and some mini games.

In the doodle, users can mix a potion using ingredients as one skull, an apple, a bone or a blue potion; each of them redirecting users to a different mini game.

Wack-a-zombie game or other in which users need to follow with the mouse a ghost in the dark are some of the possibilities.

Users are encouraged to find all mini games at the same time they discover the well-known easter eggs Google has hidden all around. Just type and search "skeleton" or "vampire" or "Halloween witch" and see the Google Search Graph entry it pops up.
