Our world is full of mysteries that seem insoluble. The mystery of Roswell, the mystery of the Kennedy assassination, giant inscriptions in the Nazca desert, what really happened to the Dyatlov group, where the crew of the Mary Celeste went in the Bermuda Triangle and many other questions remain without a final answer and decoding. This often happens for the reason that people are afraid to strain their logic and analyze the facts, which are abundant in the public domain. Something subconscious within us, certain mental blocks, do not allow us to see the obvious, but forces us to see only what is generally accepted. But it is human nature to strive to find out the truth, sometimes bitter - isn’t this what girls who read email and “SMS” of their boyfriends? And sometimes the truth is not just bitter, it is terrifying. We are talking about a cartoon that rightfully occupies a place in the “Golden Collection of Soviet Animation”, which was watched by more than one generation of Soviet children. Surprisingly, none of them saw in it anything other than the generally accepted interpretation of events. I believe that we should forget about stereotypes and try to understand what the author wanted to tell us, guided solely by logic and common sense. And accept the truth that for many years remained hidden from our consciousness, get answers to a riddle that for some reason no one saw. So, the unfading Soviet classic - “Three from Prostokvashino.”
