Have you ever been able to identify the peculiar "Mystery Flavor" in Dum Dum Pops? I sure haven't, and now I know why! Spangler candy creates the "mystery" pops at the end of a batch of one flavor when a new flavor batch is begun. In other words, between the pure flavor batches, you get a unique flavor combination. You can read all about it here in a report from mental_floss blog.
