Wheels and Wipeouts

K3 are performing a concert at a roller-skating and skateboarding competition. The 2Ds, Dwayne and Dee Dee, are there competing against others like Wheel-Surfer and Swiss Cheese (a masked contestant). The race begins and it looks like one of the contestants is sabotaging the competition, compromising the chances of the 2Ds. After investigating, K3 unmask Melissa Dubois, the organizer of the games who disguised herself as Balaclava in order to win the trophy for herself.
