Elements of Synthetic Mine

It is yet another normal day in the Nobi family. In the afternoon, Doraemon was eating dorayaki.

Jealousy took over Nobita. He wondered why the hell Doraemon was eating so much dorayaki these few days. He thought that Tamako gave Doraemon more pocket money than him. When he questioned Doraemon where he got his money from, Doraemon playfully teased him back that it was a secret.

At night, Nobtia was sleeping on the floor as usual. He woke up as he felt a sudden urge to pee. Then, he heard loud mining sounds coming from the garden. Curiosity took over him, so he went to the garden. He saw a hole and went into it.

In the hole, he saw... Doraemon mining dorayakis!
