Marta, Franek and Igor were not ordinary pupils. I mean, they behaved seemingly normally at school - they did their homework during breaks, brought their lunch (which mysteriously always disappeared in unexplained circumstances), sometimes even tried not to fall asleep during maths lessons. But on the inside - oh, on the inside there was something... unusual about them. It all started on Wednesday, during the lunch break, when Marta looked suspiciously in the direction of the minced cutlet lying on her tray. - Do you guys see that? - she asked in a whisper, leaning towards Frank and Igor. - That chop... he moved. And he winked at me. Igor snorted with laughter, but Franek already knew Marta wasn't joking. Not after the story she had told a week earlier about the jellybean that had allegedly jumped off her plate and landed on the headmaster's backpack. - What if there's something really... amazing going on in that canteen? - said Franek with a seriousness worthy of Sherlock Holmes, although slightly less elegant as he still had the ketchup from the sausages on his lips. Thus the Unusual Soup Club was born. K.N.Z. - a name invented by Igor because he was nuts about abbreviations. They decided that every day at the big break they would keep track of what was happening in the canteen and keep an observation log. Their first task was to find out why the broth last Monday was electric blue. They set up a 'base of operations' in the furthest corner of the canteen, near a window overlooking the school car park, where the school's cat - Rabarbar - was conducting his own dodgy business. Each day they also observed the cooks, who were behaving more and more... bizarrely. Mrs Jadzia, the head cook, started wearing a pineapple hat and the younger cook, Mrs Halinka, said she was communicating telepathically with the noodles. During the first two weeks, the Unusual Soup Club discovered many things, which they categorised into: "normal", "abnormal" and "definitely unexplained". Under the 'definitely unexplained' category, they had to put disappearing pancakes, sausages singing under the table and vegetable soup that started bubbling rhythmically the school's anthem on Wednesday morning. The more they discovered, the less they understood. That is, until Friday afternoon, when Igor - chatting at the window - saw something he had never seen before: a group of people in white coats came into the canteen through the back door ... and they were carrying what looked like a huge blender The friends turned into statues. From that moment on, they no longer just wanted to find out what was going on in the canteen - they knew they had to find out why the school canteen suddenly needed a blender the size of a cupboard....
