Public Toilet Training

Only in Japan do they feel the need to train children how to use public restrooms using tigers and animated poop. Even if you don't know Japanese this is still entertaining, I just don't get why this is necessary. Can't the parent's just tell the kids this stuff ? There's no need to bring poop to life or watch an animated tiger struggle.

I tried to find other videos from other countries but it seems like Japan are the only ones that do this.. truthfully I had no idea there was a such thing as public restroom etiquette, so I guess I lose this one... or do I ?
