I’ve tried all the ones JLeslie mentioned, i.e.:
Cap’n Crunch
Fruit Loops
Coco Pebbles
Fruity Pebbles
Frosted Flakes
Apple Jacks
Sugar Smacks
Corn Pops
Lucky Charms
I’ve also tried:
Peanut Butter Cap’n Crunch
Honeycomb
Super Honeycomb
Count Chocula
Frankenberry
Booberry
Frosted Mini Wheats
And probably several others I am not remembering.
The one I got most into (when I was about 4 to 8 years old, IIRC) was Honeycomb, but largely because if you collected enough box tops, you could get a Honeycomb Hideout cardboard box fort mailed to you . . . but I think I got sick of them before I had enough, and/or I just got a couple of the secret flashlight/whistle things instead, or lust decided those were better, since I could make box forts out of other boxes easily enough.
I also quite liked Cap’n Crunch for a while, but had my lifetime amount I ever wanted to eat of that and stopped before age 10, too.
Oh and I liked Sugar Smacks. I think I even ate some Sugar (now Honey) Smacks when I was in my 30’s, and liked them, but they seemed a bit much to want to keep eating them. Oh, in my 30’s, I also sort of liked Special K with dehydrated strawberries, though that’s rather milder, and I lost the appetite for them after a few boxes.
Apple Jacks are sort of good.
Count Chocula, Frankenberry and Booberry are of course sentimental Halloween-themed favorites, but not something I actually want to be eating since the initial fun in the 1970s. I have seen them occasionally re-appear in the 21st Century, at Grocery Outlet.
I had to be quite young to really be excited about sweet cereal, and even when young, I got tired of it. The people I knew who were REALLY excited by it (a few of whom remained somewhat so) were people with parents who tried to prevent their children from getting it, and/or made it into a special treat for very rare occasions. I credit my parents’ liberal attitude toward them, with my changing interest in them at an early age.
I’d much rather have fried eggs and/or toast, let alone an omelet or a good breakfast hash or burrito or something.
