Santa's trying to improve the procedure of handing out gifts, every year. This time, he invented a new type of twin ion engine which significantly increases the speed of the sleigh and makes it possible to avoid the using of reindeers, thus decreasing the amount of stress they need to handle. However, it's still a prototype and we need to be careful with it. For now, it seems there's some malfunctioning and it won't start. The reindeers are not used to this extra weight and are confused. We need a little time to fix this. Can you help me with finding the right objects?
