Everyone knows "The 12 Days of Christmas," but how many people have actually seen a partridge in a pear tree? With the power of the iReport community, we want to recreate the classic Christmas song using a mash-up of your images.

So here's the deal: in the days leading up to Christmas, we'll issue a daily challenge to capture photos and video of the items in "The 12 Days of Christmas." Then we'll put them all together and create a musical masterpiece just in time for Christmas Day.

Of course, the challenges will require a bit of creativity. You can dress your friends up as lords and film them leaping or create a cool animation of swans-a-swimming. The sky's the limit! All we ask is that you have fun.

Update: Thanks for all your submissions! Check out the 12 Days mash-up video on CNN.com.
