Shin-chan goes to the post office and gets diverted. He forgets what he was asked to do and confuses everyone at the post office. Shin-chan and his family visit a haunted house and get scared when a mummy runs behind them to get rid of his band-aid from their hand. Misae gets annoyed due to the house work, so Hiroshi and Shin-chan do the cooking. They realise Misae's situation and thank her.
