Goodwill Incorporated Knoxville is giving away a family membership to Zoo Knoxville, to the person who makes the best costume.

The catch? The majority of the costume must be purchased at one of Goodwill's stores.

Second prize gets a family four-pack of tickets to Zoo Knoxville, and third place gets two tickets to the zoo.
