See a new 'Ninja Warrior' obstacle... in LEGO

Summer competition series American Ninja Warrior is back on NBC Wednesday at 8 p.m. ET/PT. But before the show's elite athletes show us the ropes, LEGO characters are previewing one of the new obstacles we'll see this year. Presenting... LEGO Ninjago characters taking on The Big Wheel:

'American Ninja Warrior': The Big Wheel in LEGO

LEGO characters preview The Big Wheel, one of the new obstacles on 'American Ninja Warrior.'

Of course, LEGO versions of co-hosts Akbar Gbaja-Biamila and Matt Iseman appear in the stop-motion short. So do a few Ninja Warrior veterans.

Note: When LEGO characters fall on the course, it's much more graceful than when human ninjas do. (We know from experience.)
