Kellogg's wants people to make gingerbread houses out of POP-TARTS this year. Whoever makes the best one wins $15,000. They announced it with a fake listing on Zillow.
The example they built is hard to beat. It's a four-bed, two-bath home that's fully furnished. Even the bathtub and toilet lid are Pop-Tarts. (They noted that it's built on six-ten-thousandths of an acre. Here's the listing.)
Along with photos, you have to tag Pop-Tarts on Instagram or Twitter, and include the hashtag "GingerbreadPopTartEntry". You can also draw your design, if that's the route you want to go.
The cutoff is end-of-day on December 16th. You can check out the full rules at PopTarts.com/contest.
