I have a lost media but I don't know the name of this show.

Hello guys. Well, how can I start? I have a lost media. This lost media is a cartoon show of a dog, a chicken and a duck. It was aired in Brazil broadcasted in the 90's with the name "Nicolau e a turma do quintal" ( Nicolau and the backyard's gang) I don't know the real name of the show. The show hadn't credits or an opening. The only information I know is that this show was made in Eastern Europe. Well I will publish it here. The show has no voices, only background music. I admit that this show made me scared when I was a kid.

Does anyone know?
