The mystery of the missing capybara

Life in one small town was completely boring. For a long time no events had disturbed his calm, calm, like the surface of a forest lake, everyday life. But what is it? Bright posters suddenly appeared everywhere with an invitation... to the local zoo, where the day before they had brought a strange animal - a capybara. Only on the appointed day there were no cariparas... bakirabs... picarabas... oh, capybaras... there were no animals. Where did the exotic guest go? Where to look for it? Classmates Marik and Alisa get down to business, and the local policeman’s little son, Slavik, is called in to help them. Only none of this trio knows what the mysterious animal looks like... So, the adventure begins!
