What is the nastiest tasting popular breakfast cereal?!

Best Answer - Chosen by Voters

Cocoa Krispies, I had them one time when I was a kid, back when they still featured the monkey on the box. I can still almost remember what they tasted like, probably 20 years later: Disgusting. Both my sister and I thought so, and we were really excited to try them. I loved chocolate as a kid and still do, but breakfast should be breakfast. It doesn't need any added chocolate crap.

I also hate the peanut butter Cap'n Crunch. It doesn't taste like PB and it scrapes off the roof of your mouth, unless they have improved the recipe recently.

ok don't know if it's popular but worst cereal I ever had was Chocolate Honeycomb.
I actually spit it out and threw the box away.
It was horrible and fake tasting.
Second contender, Special K Chocolate
Special K+ waxy chunks of nastiness= disgusting.

I love chocolate and most chocolate cereals, but not those two!

Cookie Crisps. Begged my parents for months to buy it for me for breakfast when I was a kid and when they finally did I was totally disgusted by it.

trix, fruit loops, and fruity pebbles
i really dont like neon colored cereal.

Cheerios! not the honey roasted kind, but the plain, no taste kind, DISGUSTING!!
