Dream Uneven Bars is a Dream Event that appears exclusively in Mario & Sonic at the London 2012 Olympic Games. It is set in Grand Metropolis from Sonic Heroes. The starting Olympic record is held by Sonic at 346 points.
After the characters are introduced, the four characters are picked up and sent to the sky by four Chao. To earn points, players need to spin the characters around green and pink bars with some bars even moving. Green bars only give one point four times, while pink ones gives two points eight times.

If the player lands on it during the final countdown, they earn 10 points.
