Here Comes the Sun

S1, E49: Headmaster Crane, insisting that the Sun can rise from the West, makes a bet with a skeptical Vulture. The stakes? The loser of the bet must dress up as a silly mascot for the next Orb-O match and dance in front of the whole academy. Trying to help the headmaster, the Racers travel to different locations on Earth and the Moon, develop hypotheses about sunrises, and finally discover that the direction of the sunrise depends upon the rotation of a planet. So they fly to Venus -- which rotates clockwise -- but since they’re not able to land there, cannot confirm their hypothesis. Will they be able to prove that the Sun indeed can rise in the West, and make Vulture dress up at the next Orb-O match?
