With several million YouTube views in Japanese and translated versions (above), the Nuclear boy cartoon has become possibly the world's most viewed ever exploring the metaphor of a boy with a sick stomach to represent a stricken nuclear power plant.
It may sound kooky, perhaps excessively so, but when you put it in the context its creators intended - to explain the crisis at Fukushima to Japanese children who may not understand spent fuel pools and containment vessels - such concerns fade away. The Nuclear boy character was created by Japanese artist Hachiya Kazuhiko. He posted it to Twitter, where one follower turned it into a comic strip that a third person then animated.
The story is quite simple: Nuclear boy is sick and people are worried he is going to have a really big poo (as the translation puts it). He had people scared when he let out a loud bang - thankfully it turned out to be neither a poo or "that stinky" - so he needs to given medicine until he gets better. For Nuclear boy that medicine is cooling sea water and boron.
