The last part of episode 109 featured Sailor Moon voice actors playing parody Sailor Moon characters very briefly, and came out at almost the same time as Sailor Moon S #104, which in turn featured a boy named Shinnosuke and his mother, played by the voice actors who played Shin-chan and his mother on the other show.
The episodes are in Japanese with KIKU-TV off-air Hawaiian subtitles. There is an existing torrent containing these episodes but those are Malay/Chinese VCD rips. Feel free to put these in that torrent if you want.
This came from a multiple generation VHS, ripped to DVD, ripped to H265 MKV at low quality. There is some buzzing at the start; I took only the left channel when ripping to .mkv because it had less buzzing. I have no idea if Crayon Shin-chan was originally a stereo show.
I only got this tape for the Sailor Moon pseudo-crossover, so I don't have other episodes.
