Polish TV

On my recent trip to Krakow we would watch the TV late at night and there was a kids TV channel. This would air a semi-still shot of a fish which would blow a bubble to the surface. It was pretty weird and can I hell as like find anything on Google about it. So relaxing though when trying to sleep off a huge amount of alcohol. Can anyone find anything about this?

Also, the Simpsons in Polish was strangely brilliant!
