An idea to be put into a children's game:

Something here would need to explode. Preferably Elmo.

This game would be for very small children, to teach them numbers or reading, things children want to know about. Upon losing, the character in the game would look sad and say something stupid like "Try again, I know you can do it!" Now, there should be a random chance, let's say, 1 in 100000, that the character, upon losing, would explode into a gory mess filled with all sorts of organs and fluids everywhere. The child would be traumatized, and their parents would have no idea why, as it'd never happen again. If a parent were to see it, there would be nothing they could do about it, and the people they'd tell would just think of them as crazy people. Clearly this is what should be done with children's gaming. That is all.
