Shinchan episode (lost) that always haunts me

Hi, I'm a guy that watched Shinchan for a considerable amount of time on Hungama TV all the time for the majority of my childhood... Getting to the point, I had watched a really rare episode of shinchan, that may have been removed for being too dark for children??? The episode was normal at first, Shinchan and his friends were at school, (I don't remember all of it, but I remember some important parts) suddenly the atmosphere goes dark and they are seen in their school restroom, and the building gets destroyed and the teachers go demonic and scare the children, this happens when there is a thunderstorm outside... (in the episode of course) If you know it, and moreover, if you have a link to it, please do send it to me...
