Snacks are the same for any of the tiers. "Snacks" are any single item that has a sticker (or printed on it) of a purple square split into four smaller squares (two purple, two white) with the Disney "D", a standard "d" "p", and a drink container inside the boxes. Items at Epcot's various festivals are included if they have this symbol.
Examples of some of these items are Oatmeal, ice cream bar, bottle of water, popcorn, coffee, muffin
