Which kid in America has the most creative Halloween costume in the pumpkin patch? That's what we intend to find out with your photos and the help of celebrity judge Heidi Klum, who will select our grand prize winner.

The grand prize? Patch will whisk the winner to New York or Los Angeles on a three-day, two-night trip for two that includes a meet-and-greet with Heidi, plus a donation of $1,031 to a local charity of the winner's choice. Nine runners-up will also get a $1,031 donation from Patch to a local charity of their choice.

Entering is easy. Just upload a photo of your child, 12 years old or younger, in his or her Halloween costume. Entries must be made by the parent or legal guardian of the child photographed. Full rules are here.

Submissions must be received before 9 p.m. on Halloween (Oct. 31).

Good luck and be sure to support Heidi Klum’s efforts to feed the hungry. Visit Trick or Treat for UNICEF! Find more of Heidi’s Halloween favorites at heidiklum.aol.com.
