"And who are the fixies - a big, big secret!" - that's what the song about the fixies sings. Until recently, people knew almost nothing about these little people who live inside cars and appliances. Fixies take care of machines from the inside, cleaning them, lubricating them, fixing minor malfunctions. They are skilled and diligent craftsmen. Fixies are used to hiding from people, but they are everywhere: in computers, refrigerators, TVs ... Everyone remembers the cases when a non-working device suddenly began to work if it is lightly tapped. It's simple: a fixer woke up inside and made everything work. And now you can watch cartoons about these mysterious hard-working people and get to know them better...
