The Canadian version was puffs, rather than like rice krispies. You've had an inferior version of the cereal for your entire existence so I can't blame you for thinking it's good. Here's a scan of the old Canadian box:
Unfortunately the cereal itself is a render rather than a photo, bit you can kind of get the idea. Notice the difference in colors (only 3 colors), and more importantly notice the makeup of the cereal: Wheat, corn, and oats.
A few years ago my wife was on a trip to the States with her dad and I asked her to bring me back a box of Fruity Pebbles, knowing that they were still available there. Imagine my horror to find that the cereal was completely different.
It depresses me a little every time I think about it - the version from my childhood no longer exists, and likely never will ever again.
Here's a photo of a variant of the cereal, also Canadian, with an actual photo of the cereal itself; note how the cereal is round:
It was more like a fruity Corn Pops.
