Two Big 12 mascots will take part in a 16-team league this season, with weekly matchups determined solely by fan voting.
You can vote here on the Capital One Mascot Challenge Facebook page.
Oklahoma's horse, Boomer, will take part in the competition.
Each team's mascot came with a mock movie trailer. They're hilarious.
You can see Oklahoma's preview video here.
Iowa State's Cy the Cardinal will also take part. See his trailer video here. It's pretty fantastic.
"Hey Big Bird, you lost?"
"That bird cannot dance."
Oh, no, cheerleaders. He absolutely can.
