I loved Ghostbusters cereal back then! And TMNT and Nintendo Cereal System as well (at least I think NCS was made by Ralston).
Ghostbusters cereal is even part of one of my earliest memories of getting in trouble. When I was about 7, I had to go to the dentist. The night before my appointment I was told by my dad not to eat anything beforehand. But when I woke up the next day, I couldn't help it-I poured a bowl of GB cereal and ate it. Thankfully, all I got was yelled at-in fact, after I woke up after whatever procedure the dentist put me under for, we went to the store and my parents bought me a big box of some kind of dinosaur cereal.
