I do not recall the metro warning signs in France. I do remember them in Japan. It's because the Japanese ones were funny and draw you in to a story.

You could have the following without the pictures: https://pradt.co/imgs/poster/pleasedoit02.gif

There's different styles to this, there's variations which are more Disney or Anime like, what's the issue? The point is to draw attention, I don't see what the need is for the ostensible seriousness, if it's not effective at educating and drawing people in to your message.

I'm surprised you don't remember the Rabbit of Paris Metro: https://en.wikipedia.org/wiki/Rabbit_of_Paris_Métro (maybe they changed it?)
