"Fun" toilet paper?

I thought this was quite interesting. By accident, I grabbed the "kids-fun" toilet paper. So let me get this straight - putting these little figures on toilet paper makes it FUN to wipe? What's fun about wiping? And perhaps more importantly, what's fun about these strange creatures? I can identify a cat and a dog, but the two in the middle? Who knows. Maybe it's because I don't have kids, but this doesn't seem like the most likely way to get kids potty trained...
