Story : Plif and Plops build themselves a nice, fast racecar, but they don´t want to have Plummy with them on their fast drive. He turns into a road block, then into a traffic light to stop them, but they constantly escape him by playing a trick on him. Now it´s his turn to play a trick on them: the car runs out of gas and Plummy quickly morphs himself into a petrol station, just that far from the car that Plif and Plops have to push it to the petrol station. The moment the both exhausted Plif and Plops insert the gas pump into the racecar, Plummy turns into a pneumatic pump. So the car is filled with air instead of gas and soon turns into a giant balloon, and all three of them go off for a ride across the skies...
