In the old attic

Once, in the old attic of an ordinary apartment building, a fifth grader Sasha Kukushkin found a book. It was a "full magic encyclopedia." Oh, how he needed her! Indeed, with the help of just one short poem from this book, all the lies instantly becomes true: and even a deuce in mathematics will immediately turn into a five - if there is at least one person who believes it. Fortunately, there is a little gullible loll nearby!
Only the trouble is: even the most harmless, at first glance, the lie pulls along the long chain of unexpressed events. Monkeys and bears settled in a city apartment, the rivers suddenly and catastrophically come to the city, and any attempt to correct the situation leads to even more terrible consequences: a breakthrough of the dam, an accident at the power plant, fire ...
