There is a new Obstacle Course in Yoko Park -- a fun way to stay active and be healthy. For the opening, Ranger Loops will hold a race to see who can go through the obstacles fastest. Oto wants to be in tip-top shape for it, so he chooses a traditional workout with the Ranger and Ronnie the Workout guy. Vik and Mai think that doesn't sound like fun. Instead they have a very active adventure with Yoko as they searching for the imaginary Jewel of the Jungle. When race time comes, Oto feels he will win. But, Vik and Mai have a surprise for him. By playing really hard with Yoko they are in good enough shape to win, too.
