However, the mouse robot misinterpreted Sewashi-san’s instructions. Unfortunately, the mouse robot ended up eating one of Doraemon’s ears.

Since that incident, Doraemon has been fearful of mice.

To add to the mayhem, the situation took a turn for the worst when Doraemon was rushed to the Robot Hospital. In a comedy of errors, he had his ears accidentally removed by the doctor.

The origin story of Doraemon continues with his lover, Noramyako, a robot cat, seeing his missing ears.

Noramyako was rather tickled by Doraemon’s missing ears. This saddened him.He tried to cheer himself up by drinking the happiness drug, but he mistakenly drank the sadness drug. The effect of this was that Doraemon ended up feeling sad for three days and three nights long.
