Peak Popularity: Late 1980s
Dino was the pet we never had and always wanted, so when they put his visage on a cereal box, we blew fits in the supermarket isles to get our grubby hands on it. Unfortunately, the rest of the world didn't feel the same way, and Dino Pebbles disappeared from shelves by the time the '90s rolled around. Despite not having marshmallow bits, Fruity Pebbles prevailed. It was either a conspiracy, or due to the fact that Dino Pebbles were vaguely reminiscent of fluorescent dinosaur turds. We're still not sure.
