A very important coin

Tonight, Yoshi had learnt the importance of a HK$10 coin (=US$1.25). Grandma gave him a coin, and he kept that in his pocket the entire car ride (with his right hand in it, worrying it would fell out). He knew that coin would meant another twist and turn to collect his favorite shinkansen (train) toy capsule.

So far, he had collected 3 of those, luckily, he didn't get another bridge again (which has no train inside). I'm sure by the end of this trip, he would have a long rail...
