This has got to be one of the most ridiculous things I have ever seen.
I was hoping it was a joke, but no it's available for $39.99 on Amazon.
I have potty trained 3 kids, you know what we did to keep them entertained while they sat on the potty? We sat in the bathroom with them and read books or sang songs. As they got more used to the routine, we kept some books in the bathroom for them to look at on their own.
