- Breakaway Pop Hit:
- "Dango San Kyoudai", the biggest-selling Japanese CD single of all time, came from an animated short on this show.
- A song from the show about a mushroom wanting to leave the forest and go on an adventure (set to traditional Russian folk music) became a hugely popular hit and charted on the regular Japanese music charts. It was even sung live by the hosts on NHK's New Year's Eve special (one of the most watched shows of the year in Japan).
- Keep Circulating the Tapes: While the animated shorts have home video releases, they do not get re-released after a series ends its airing. Used copies of home video releases are expensive to buy. There are videos of the animated shorts on video-sharing websites but most of them were removed by NHK. Fortunately, there was a rerun of old animated shorts in 2010 and 2011.
- Missing Episode: As with other television shows at the time, most 1960s footage of the show are considered lost, due to tapes being reused for another recording since they were expensive. Despite this, there are few surviving clips from the decade, which can be seen in the NHK Archives.
- Talking to Himself: Princess Spoon's Swing Kitchen has two voice actors, which are Keiko Han and Toshihiko Seki. The former voices all female characters and the latter voices all male characters.
