As soon as the Christmas season is over, a strange fever breaks out in Basel: the Carnival fever! Children sell Carnival goodies on the streets, and from the basement and living room windows, you can hear the sounds of drums and piccolos. The whole city is infected with Carnival fever, and everyone is preparing for the three most beautiful days of the year. Alina, a cheerful girl with dark red hair, bright eyes, and a joyful laugh, is also looking forward to the Carnival.
