The Mouse and The Bomb

Doraemon is even more scared of mice than Mom is and starts shooting at everything that moves when one turns up in the house.

Doraemon pulled out a "Bomb of Mass Destruction" causing him to go out of control, but Tamako and Nobita calmly told him and lied about the mouse is already gone, as they still hunt for the mouse while Doraemon is calmed down on the corner. Until Nobita's father, Nobisuke Nobi, came back home from work ruins it by saying "There's a mouse over here", creating a conflict of the whole family for spilling the truth thanks to Nobisuke, while Doraemon looks at them with confusion, ending the episode.
