Off Road Rage/Fitness Crazed

S1 E14: When Dan opens a package that allows him to flash-modify any vehicle he chooses, he wants to use it to help Troll win the Iron Bay Off Road Challenge and finally get Troll’s family name on the cup, but Troll wants to win with honour and will have none of it. Only Terrance and his Dad stand in the way until Copernicus also enters the race, determined to get his hands on the alien device at all costs./Tired of being weaker, slower and less athletic than Troll, Dan gets his chance at redemption when a weightlifter’s belt arrives that instantly pumps him up to Mr. Universe proportions and allows him to do superhuman feats of fitness. When the townsfolk get a look at super-fit Dan, they want in on the action too. Soon the whole town is so buff that even babies are ripping doors off cars. But the effects of the belt are only temporary, and soon all their new bulk settles elsewhere in their bodies. With the populace barely able to move, they’re easy pickings for Copernicus and only a little Troll sweat can save the day.
