One ill-fated morning on Bald Mountain, right on the territory of the Central Academy, there appeared... appeared... in short, now there was something that absolutely should not have been there. And if the Mayor of Central and the City Council had found out about this, then loss of reputation, falling face down in the dirt and simply a scandal would definitely not have been avoided. Mr. Bey-Brynchalov, the Rector of the Academy, found all this very unpleasant and out of hand, so on Bald Mountain a couple of hours later, the great and inimitable Guignol Guignol himself, a specialist in solving problems of any complexity, was already shining with a crimson jacket and glinting with the knob of his cane. Only he was able to figure out how this... it got there, find a way to return it to where it disappeared from, and explain to the public of the city what... well, let's say, aliens have to do with all this. And it began!
