I've got the Beauty and the Beast sweet shop for 2 days now and didn't drop 1 lolly. I'm building now the sweet shop for Frozen and will see how it goes tomorrow. But overall, after I made 1 dress, I just got stuck because of lollipops. I sent characters on long tasks -nothing. I sent the bread maker and librarian on short tasks whenever I could in my breaks or something. Nothing again. I won't invest anymore time in dresses, if it happens, great, if it doesn't, that's it. The buildings seem worthy somewhat, so probably these + triplets are best gain.Not sure if this will help but I just realised the sweet shop and confectionery drops lollipops I think. you can buy these buildings with chocolates.
