Uhmmm, I know where a Haribo factory sale is. It is not far from my school. Haven't been there myself yet but my Mum once brought some special gummybears (fruit/yoghurt twirls-thingies) I've never seen in a shop before. I could get a bit of everything (You can mix some bags yourself I think) except there's something you really don't like.

Gah, those waffles can be cruel xD They are tasty but if you tend to eat too many, you'll feel sick later on. That's what happened to me the last time I had some xD
Never heard of the other two, even though most of the bakeries (Bakerys? Bakers? @.@) here sell spiral shaped 'Schnecken' with raisins and sugar icing which look a tiny bit similar.
Or are Zeeuwse bolus 'Zimtschnecken'? (Cinnamon slugs)
