As it is hot, Shin-chan forces Misae to buy ice crushers. He eats a lot of ice candies and upsets his stomach. Shin-chan and Kawamura take their dogs for a vaccination. Shiro, courageously, steps forward and gets himself injected. Shin-chan and his family go camping. They set a tent and cook food. They stay awake in the night as it rains. And in the morning, they all fall asleep.
