I remember Mud & Bugs! I used to beg my mom to buy it but she said it she might as well give me a bowl of M&Ms with milk because those cereals were like eating candy for breakfast. <---Mom
The only one I remember eating was Team. I recall a few others from seeing ads. Note that almost all of them were using a recent movie's popularity to increase consumer recognition. That usually guarantees a short life span.
I just barely recognized one or two. My mother wouldn't buy commercial cereal, if we wanted it, we had to buy it ourselves. She bought oatmeal and generic cheerios, or we ate eggs and biscuits (from scratch).
I also didn't have television until I was 7 or so, and then we never had cable, so not much commercial watching.
It means I always lose at quiz type games with pop culture questions.
I remember a lot of those, especially C3POs and the Nintendo Cereal System.
We never had that variant of the TMNT stuff (with the chex and marshmallows), instead we had these really dry, unpleasant green-coloured turtle head shapes. It wasn't very good.
