Kenichi becomes worried when he hears of the legend of the snow queen, and Kemumaki and Kagechiyo start to make things worse.
Upstairs, Hattori and the gang are watching the weather forecast. They are excited when they hear that it's going to snow, but are horrified after Hattori tells them about the snow queen, who apparently petrifies people by letting out an icy blast from her mouth.
Next morning, Kenichi goes to school, disgruntled. Kemumaki and Kagechiyo are hiding behind a tree and disguise as the snow queen to scare Kenichi. Later on at school, he tells Kemumaki and Yumeko about his ordeal.
On his way home, Kenichi encounters Kemumaki and Kagechiyo again, disguised as the snow queen. They scare Kenichi to the point of knocking him out. Later on, Hattori and the gang find Kenichi, still unconscious. On revival, he tells them about the snow queen. Hattori says that he must be joking, but Shishimaru realises that it was one of Kemumaki's tricks.
Later on, Hattori and Shishimaru disguise as the snow queen to scare Kemumaki, but due to an accident, they are exposed. Hattori and Kemumaki are then engaged in a fierce duel, but meet a walking, talking snowman! Kemumaki runs away, but Mr Mitsuba reveals himself, and Hattori apologises for mistaking him for a snowman due to his plump figure.
