Foreign citizen Karbofos (allusion on Karabas Barabas) steals a rare species of striped elephant from a city zoo. Famous Kolobki brothers tackle the investigation. In a souvenir shop, Karbofos obtains a certificate confirming that he had bought a porcelain elephant. Using this certificate he tries to get on a plane. Luckily, the ingenious Kolobki arrive just in time to lure the elephant away with cod-liver oil and shoot Karbofos down with a balloon gun. (wikipedia)
