Bunny-Reader and the Missing Letters

There is a commotion in Alphabetsville again! This time, amidst the hustle and bustle of a grand celebration for Slavic Writing Day, some residents of the city go missing. Raechka and Bunny-Reader set off in search of them. During the investigation, they learn about the parts that can make up a word, what unpronounceable consonants are, and why verification words are needed, as well as getting to know foreign guests and the ancestors of the letters of the modern Russian alphabet.
