Pipì, Pupù and Rosmary are at the arctic polar circle and, given that they arrived there during the time when it is perpetual night, they don’t do anything but sleep. At one point, however, they are woken up by a goose who announces to them, preceded by a trumpet sounding, that it is Christmas eve. Our three little friends decide to get up and, in front of their very eyes, Father Christmas passes by on his sleigh filled with gifts. A little further down they also find some beavers, a crocodile and some fire flies who are decorating a tree, and a bear is blowing soap bubbles which, in contact with the air, turn into ice. Pupù, who is fascinated by this, gets trapped inside one of the bubbles which floats up to the top of a snow-covered mountain and causes an avalanche as soon as the bubble starts rolling down. The avalanche sweeps away the christmas tree and all the glow worms that were helping to build it. When they realize they won’t be able to free their friend Pupù who’s trapped inside the bubble, our “survivors” are forced to beg the Narrator to go and ask the Sun to come out, at least for an instant, to thaw the snow around Pupù and the fire flies. The Sun consents and exceptionally shines for some minutes, thawing the snow of the avalanche but also all the snow of the polar circle, which infuriates Father Christmas whose anger, thankfully, is only shortlived.
