Game is fine, ads completely inappropriate for children

I downloaded this game for my preteen son and, while the game was fine and just what he was looking for, I had to erase the app because of the pop-up ads. They were optical illusions that greatly resembled naked female anatomy. Fine for consenting adults. Not okay for kids. I have downloaded other sports games for him and not seen these ads, so I can only assume it is this developer.
