Like the Halo cards, these are cello bags with the same design. Thye come with a pink or yellow insert, with the yellow coming with the older dispensers, and the older style candy packs.
As you saw on the Halo Card page, the NF cards always have the blue candy packs. The above three bags have the blue candy packs. Guess what, they're NF, too. Well, almost. The Octopus/Blob is actually footed, but it has no rear spine. This means that it was one of the first to come with feet. So, it makes sense for it to have the blue packs.
