They were the precursor to Chex Mix and tasted a heck of a lot better. The snack items were, in my opinion, a better selection, as well. As I recall, they were faced with people making them at home when the Chex cereal people started putting a recipe on the boxes instructing '70s folks how to make them. Of course this was a marketing vehicle. One box of each three cereals were required, even though only a cup of each type was needed. Not too long thereafter, DooDads changed their seasoning and packaging. By that time, Chex had started creeping onto store shelves in an already-made incarnation which is what we basically know today. DooDads died and I mourn the loss. Nothing can compare, to me, with what they were.
