I'm from Savanna, Illinois and we were always going to the river to fish or as we put it "take the dogs to the river" and one staple was Fizzies for me. Golly, Fizzies were popular and I loved them. I'd even put them in my mouth and feel the vibrations as it fizzed.
They turned out to be deadly, of course. I checked on Fizzies and if you remember them you can read about their sad demise at this site:
