Kuzya the housekeeper, invented by Tatyana Alexandrova, is the keeper of the hearth, the invisible assistant of the owners. There are both evil and greedy among them, but he is kind. He is seven centuries old, which is equal to seven years for a human. He has many comrades just like him. Just listing their names takes up an entire paragraph in the book. For the first time, he appears to readers and viewers disheveled and dirty, but in fact he has blond disheveled hair that sparkles like gold.
