Fruity pebbles...

Hi Reddit, Okay, we'll you know the fruity pebble commercials? And how it says you eat 64 pieces at a time.. It takes my son about an hour and a half to eat his cereal because he actually counts 64 pieces! I've explained to him he doesn't need to do this, but he says the kids in the tv told him too. I've also tried getting him other cereal, but he will NOT eat it. He only eats fruity pebbles for breakfast, every morning. That's all he wants. What do I do?
