Episodes 1 and 2 were made by Soyuztelefilm in 1986, 3 and 4 by T/O Ekran in 1987.
Later the characters (Brothers Pilots) of this animation were heavily used by Tatarskiy's Pilot TV, in particular for the series Attic Fruttis and Academy of own Arrors.
The name of this animation film is a pun of a popular Soviet TV series Investigation Held by ZnaToKi.
Foreign citizen Karbofos (allusion on Karabas Barabas; also a soviet term for Malathion insecticide) 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.
