It looks like a job for Elmo, not Superman.
Okay, I realize that it is essential to teach children potty training and bathroom etiquette, but still this is just the kind of ridiculous commercialization of comic book characters that makes me flaming mad! Not only does it render classic characters as silly cartoony stereotypes, which will only further add to the stigma that comics are a children's medium, but it also degrades the very essence of heroism to the level of teaching kiddies where to pee and poo.
Obviously it can be difficult to establish a method of potty training that works for each individual child and often the best way to do it is to make it seem fun and an important part of growing up into a "big boy" or "big girl", bit is it really necessary to drag beloved superheroes literally into the crapper while doing it? I don't think so. There have been plenty of books on potty training before now and many of which have proven to be an effective way of approaching the subject in a manner that is interesting to young kids, however this is just an insult to comic book writers, artists, and most importantly the fans.
In addition, superheroes aren't really something I think children should be exposed to at such a young age.
First of all, they are violent and are about enforcing authority over the world. This doesn't mean that they encourage such ideas, but rather that they expose the dangers of people who possess power over others.
Secondly, superheroes have powers which children don't. For example, many of them can fly and I've yet to meet a child who could fly... cape or no cape. I can just see it now: hundreds of children jumping from the edges of urinals, toilets, and bathroom sinks whilst laboring under the misapprehension that if they can go potty like Superman then they can fly like him too.
Thirdly, I just don't think teaching kids to trust adults in weird costumes while using the restroom is a safe thing. it doesn't help that one of the superheroes' name is The Flash either. Seriously. Did this not occur to anyone?
And finally, this book comes with superhero stickers as a reward for successful potty usage. Isn't giving stickers for going to the bathroom going to result in stickers being placed randomly all over the surfaces of toilets, sinks, bathtubs, etc.? Does the author of this book have any idea how frustrating it will be for parents to have to scrub the sticker's adhesive residue off of porcelain? No, this is just a bad concept all around.
What's that? Is it a bird, is it a plane? No, it's the collective sound of our superheroes' legacy going down the toilet!
