PEK - Pranksters Elite Club
They call themselves PEK - Prankster's Elite Club, and they refuse to be bored. A new boy starts in the class and he is welcomed with an anaconda prank.
The class has to spend the day collecting waste, but Nicolai is excused because of two broken arms. When PEK realize they are not really broken, they initiate a plan to expose Nicolai in front of the class.
