One day, Noby was getting into a panic because he would have a huge exam tomorrow. He shouted and entreated Doraemon's help. Doraemon got angry and said to Noby " You don't study at all. You are a lazy bum." Noby promise that he would study in future. As there is no other choice, Doraemon took out "Memory Bread" Whatever on the page transferred to the bread will be committed to memory when people eat it. Noby was pleased that he could memorize answer instantly. He completely reassures, so he played video game while eating a lot of snacks. There were a lot of delicious dishes for dinner because Noby's mother cheered up Noby. He started to prepare for the test at night. The exam covers a lot of stuff, so he had to eat a lot of pieces of bread. However, he ate snacks and dinner too much so he was not able to eat them. Then Doraemon forced Noby to eat. The day of the exam, Noby suffered from a stomachchache and could not get out of the bathroom.
