In Doraemon, Daxiong's father reduced the hanging fish in episode 345. In the three-legged competition of the sports meeting, Nobita was drawn into a group with Pang Hu. Pang Hu is very concerned about the ranking, so he wants Nobita to give up taking part in the three-legged race. In fact, Nobita also hopes to run as fast as Pang Hu, so Doraemon takes out the human train combination and gives it to him. As long as you put the chimney of this prop on your head and swallow the coal with water, you can run at an amazing speed like a steam train full of power.
