Toilet Paper Pals

Okay, we totally made up the name "toilet paper pals" because these are sold by a Japanese company and we don't read Japanese. But they're beyond cute and we're wondering if they might be fun incentive for kids who are toilet training.

We spotted these on Fancy Schmancy who converted the price into US dollars (about $47) and provided a link to a site in Japan called Rakuten. Has anyone seen anything like this in the States or is this just another example of extreme Japanese cuteness?
