It’s a cracker, but fairly iconic due to the shape. Very popular snack for toddlers/young kids. They’re fairly tiny, so not as big a choking hazard. They go back to the 60s, so many of us have our own fond memories of them as children. As an adult, I still find them fun for their shape, but Chez Its, or at least the Aldi knock off I get, are much cheaper, though less exciting visually.
