Fixiks are very hard-working people, they always do something. Today their help was necessary at the Centre of Children’s Oncohaematology and Bone-Marrow Transplantation of Okhmatdet, and here they were! First of all, Nolik decided to check how strong the children he met today were. The children were happy to demonstrate their strength and beat easily naïve Nolik at tug-of-war. As a punishment for the lost competition Nolik had to drive all the winners in his speed racing car. Children liked this race very much! Well, because the principal obligation of Fixiks is to fix everything what requires fixing, Simka and Nolik, having gathered the children’s support, made a fixing session for each of them, using their magic device.
