The cast included Grzegorz Kwiecień, Krzysztof Szczerbiński, Joanna Pach and a famous Polish celebrity actor Jarosław Boberek as the voices for various secondary characters, most notably Peacock and Hummingbird.
The stories focus on the adventures of a detective duo; Hip-Hip (a pink hippopotamus) and his assistant Hurrah (a purple weasel).
All animal characters on the show appear to operate by very silly logic (similar to that of Winnie-the-Pooh) and are usually puzzled by the most basic phenomena.
However, the thief, who turns out to be a magpie, claims she is not responsible for the crimes she committed, and the animals put her on a trial with Hip-Hip as the judge.
In the end, they all learn that the magpie's actions (stealing shiny objects) were strictly motivated by her instincts so she can't be punished for her "crimes".
