Shin-chan goes to visit Hitoshi. They play together and draw on each other's faces with permanent colours. Hiroshi, Misae and Shin-chan take part in a fishing competition, and instead of fishing, Shin-chan pulls out the wig of the man sitting beside him. After Misae locks Shin-chan in the wardrobe, Shin-chan climbs on the roof and chases a mouse, and scares Misae with a toy mouse.
