Captain Crunch, Corn Flakes, Cheerios, Coco Puffs, Fruity Pebbles, Reece's Puffs, Cinnamon Toast Crunch, Rice Krispies, Corn POPs, Trix (original shaped ones), Lucky Charms, Kix. I think I named all the brands I like
Cinnamon Toast Crunch and krave are the best cereals but lucky charms with just the marshmallows, and fruity pebbles are only nice when they're not soggy (that also applies for any cereal)
I'll be the old man here and say that I prefer to eat Raisin Bran Crunch (especially the cranberry one)
If not then Honey Bunches of Oats w/Almonds works too.
