By the way, this cartoon is nowhere to be found now.
This is "Peter and the Wolf", season 4, episode 26, or simply episode 106.
It's not available anywhere, it was even on YouTube, but it's been deleted now.
And by the way, after this season the series was closed, it is no longer shown, although it used to be shown all the time in Carousel.
By the way, there are many interesting clues, many of which were cut by the censors, even when they were still shown.
