Jan Kowalski's mechanic
Żarcik is Jan Kowalski's mechanic.
Żarcik is painted dark green, with lighter green on his doors, decorated with red and white checkered decals and the number 15 printed in black.
- Żarcik not only helps Kowalski prepare for his races; he helps him pull his pranks as well. This devious mastermind always knows where to find the props they need. And if he can't find them, he can make them. Żarcik is truly Kowalski's wingman when it comes to pranks… except when they are pranking each other!
- Żarcik is "joke" in Polish, which is a reference to his love for pranks and practical jokes.
