The Happy Halloween doodle is one the Google Doodle team put together each year, but what usually is a simple illustration or animation has this year become a full day of activity where the doodle team physically carved 1000 pound pumpkins, at Google's headquarters in California.

The team placed six giant pumpkins on bales of hay and embarked on a group mission to carve the companies name into the pumpkins. While the challenge may appear to be a fun afternoon activity the Doodle Team had to be extremely careful while handling the pumpkins because of their size and weight. The heaviest pumpkin weighed 1,298 pounds.

If we are not careful the whole pumpkin could collapse, so we want to make sure they are creative, beautiful and artistic, but we also have to make sure they are structurally sound said Stephanie Boudreau, the project's co-lead.

The size of the pumpkins seemed to pose the biggest obstacles for most of the doodlers; one had to use a saw to carve her letter, as the pumpkin was 6 inches deep.

A regular pumpkin is about human head size, and this is much larger so there is a shift in dynamic instead of feeling in control you think that at any given time this could potentially consume you, said another doodler

The doodlers felt added pressure having the world watching while carrying out such a detailed task, one doodler, Mike Dutton explained. I spent the most part of the morning figuring out which part of the knife was sharp, he said in a behind the scenes video.

The whole process can be seen in this 41 second time-lapse video released by the doodlers.

The Google Doodle was born in 1998 when founders Larry placed a stick man behind the second o of the Google Logo to mark their attendance at the Burning Man festival in the Nevada desert. Once the Doodles were received well by users they became a regular occurrence to mark events and national holidays on the search engine home page. Today the Doodle's mark many anniversaries as well as holidays and events. The doodle team has created over 300 doodles for Google.com in the United States and over 700 have been designed internationally.
