I LOVED THESE. Those silly rubber "Poppers" that you'd flip inside out, place on a table, and watch it scare the crap out of you when it finally popped and righted itself. Admit it, you flinched every single time.
I always wanted one of these but instead I had a small Pantech flip phone whose only game was called aqua pang pang (and I never figured it out). But three years after I got that flip phone I got an iPhone, so things worked out pretty well!
