To complete his herbarium, Piu Piu would like to go to the mountain to look for a very rare flower. Enthusiastic at first, Molang proposes they leave at once, but Molang soon loses its will. It's a steep mountain... Once they reach the shelter, Molang regains its strength and sings all night long. In the morning, Piu Piu tries to wake it up... in vain... Piu Piu sets off alone.
