In the middle of the colourful courtyard, between the swing and the sandpit, lived the world's funniest soap bubble. Her name was Tissue Paper and she could make the funniest faces. One morning, Tissue Paper was flying over the children's heads when suddenly.... 'HIK! - she heard a strange sound. It was a hiccup! 'HIK! - again! The bubble shook so that it looked like a balloon in the wind. Little Christopher and his cat Psotka looked up curiously. 'The tissue paper has the hiccups! - laughed Psotka and twisted her moustache. Together with Christopher they set off to help the bubble. They had a hundred ideas: they jumped on one foot, sang a loud song and even tried to frighten the hiccup with a menacing face. But each time, the tissue paper only made a bigger HIK! Suddenly, as they all jumped up as high as they could, something very strange appeared at the end of the garden.... And then they heard the loudest 'HIK!' in the world!
