Pebbles Cereal (Fruity & Cocoa)
Fruity Pebbles and Cocoa Pebbles — the crispy-rice cereal fronted by Fred and Barney, with commercials built entirely around Barney's schemes to swipe Fred's bowl. "Yabba-Dabba-Delicious!" and, inevitably, an outraged "Barney! My Pebbles!"
Post introduced Pebbles in 1971, named after Fred and Wilma's baby daughter, Pebbles Flintstone — it's the oldest cartoon-licensed cereal still on shelves today. The two flagship varieties, bright Fruity Pebbles and chocolatey Cocoa Pebbles, were crisped-rice bits that turned the milk a fun color.
The ad formula ran for decades and is the real memory: contrary to how many people (this site's owner included) remember it, it was Barney Rubble endlessly disguising himself and scheming to steal Fred Flintstone's Pebbles — and when Barney pulled it off, Fred's exasperated "Barney! My Pebbles!" and the "They're Yabba-Dabba-Delicious!" sign-off closed the spot. The bit was so consistent that a generation grew up thinking of it as the Flintstones cereal, even though the brand name is simply Pebbles.
Half a century on, Post has spun the line into dozens of flavors and limited editions, but the core two — Fruity and Cocoa — remain among the most enduring licensed cereals ever made.
