A few months ago, I came across a strange YouTube video that showed some footage of an unknown horror (?) episode of Crayon Shin-chan. If I remember correctly, there was one scene where Nene was putting on a play with her other friends, and her stuffed bunnies was the audience, clapping with their long rabbit ears while wearing nice suits, while sitting on tables from a fancy restaraunt. Then, there was one scene where a stuffed bunny took Masao away while he was naked, and he was screaming and crying for help while being carried away. I think this episode might've been one of Nene-chan's nightmares. I was trying to look for the episode in full, but I havent seen any info anywhere. Due to its creepiness, after I watched part of the YouTube video, I deleted it from my "History" tab from my YouTube account, and now I coundn't find the video with the episode footage. I don't even known if it was dubbed in any foriegn language other than its original Japanese version. I also think it might've been one of the earliest Crayon Shin-chan horror episodes about Nene's stuffed bunnies coming alive, since it looked like it was made in the mid to late 90's. If you found any info or found the full episode, please comment below.
When I saw the episode's footage, it was actually a real episode, since the animation and character designs are exactly the same as the other Shin-chan episodes and the animation looks like it was made in the mid 90's. Too bad I couldn't find the video with the footage. I tried searching it up (The video's name is in Japanese), but I couldn't find it. I shouldn't have removed the video from my "History" tab.
You are very close, but unfortunately, that's not it. The episode's title includes one stuffed bunny coming alive and getting revenge. The episode I explained is entirely different, as it has almost all of Nene-chan's stuffed bunnies coming alive, and Nene's friends being in the dream too. I've only seen clips of it on the strange video I've seen and I haven't seen the whole episode.
