Do you remember eating colorful rock candy. What happened to that. I haven't seen it in ages. I found some on the Internet but haven't seen it in a shop for a long while. But I guess I seldom browse in candy shops. I no longer feel the strong pull of sugar addiction as long as I consume very limited quantities of sweets.
These images remind me a lot of rock candy. Guessing which of the above matches the name is left as an exercise for the viewer.
