Query: the grandkids aren't interested

This toy doesn't do anything aside from lighting up, and the grandkids, 4 and 2 yrs, aren't interested at all. They like boats and other bath toys. I also don't like is that it is not sealed and slowly fills with water which is a pain to drain after the bath. I don't want to just let it sit with water and then grow mildew.
