Shin-chan helps Misae in the house work, but draws pictures on the walls and on his and Misae's face with the permanent marker when Misae falls asleep. Hiroshi fails to control his laughter. Shin-chan and other students learn about tadpoles in school. Masao and Kazama bring tadpoles school. Yoshinaga puts the tadpoles into the pond after knowing about their life when they grow up. Shin takes a bath with Misae because Hiroshi had to work late. In the process, Misae has to refill the bath tub multiple times because Shin kept putting things in (ex. a beer Hiroshi most likely left for his bath, mud or dirt). In the end, Shin pees in the tub and Misae forces Shin to take a shower, in the process Shin knocks down Misae's new expensive "SAKIO" shampoo and it spills in the drain; Shin then turns the water on.
