To the American brands in Germany:
- Fruit loops: do you mean the Kelloggs-product: yes, we have them, also other Kelloggs-stuff, but not as many as in the USA.
- Coca Cola and Pepsi: for sure, but the other lemonades of these companies are different. Sprite is the same, I'd say. With "Fanta" (by CC) you have to be careful, because the recepies are different in some countries.
- M&M's: yes. In the 70ies they took over the old German brand "Bonitos" (with smileys on). Childs of the 70ies -like me- have nostalgic thoughts about "Bonitos"
- Hersheys: sometimes you can get them, but we prefer German, Swiss or Belgian brands, sometimes Swedish.
- Skittles: never heard
- Oreo cookies: I think so, but under annother name. In Holland and Britain you can find them more often
- Kool Aid: never heard
- Cup O'Noodles: this kind of stuff, yes, but under annother name. Very cheap in Asian supermarkets.
- Ritz Cracker: yes, but rival-companies are more known
- Lay Chips: yes, but in Holland you find more sorts of them.
- Doritos: yes
- Cheetos: I don't know
- Cheese-its: yes, but under the name "Scheibletten", made by Kraft. No-name-Cheese-its we have also a lot.
- drumstick: under the name "Cornetto" (just today I ate a "Bottermilk fresh"), made by that company with different names in different countries:

- funyuns: with other names from other companies, yes
- pop-tarts: I don't know
- Nestlé is a multinational company (like Unilever), headquater in Switzerland.
- Reddi-whip: from other companies, yes
- Spagehtti-os: same
About Chocolate and Sweets you must know, that they are a lot of brands in several countries, but very often they are all in hands of a few multi-national companies, like Nestlé, Unilever, Kraft-Jacobs-Suchard and so on.
A friend of mine works for the biggest manufacturer of choclate-packings. He told me, that except 3 or 4 big companies only a few small independent choclate-makers are existing.
