Sometimes they're shaped like bears. I seem to recall hearts at least once.
I like questing in the candy aisles at the drug store around the holidays, because that's the reliable time and place to find "Milk Chocolate Flavored" foil-wrapped treats. I don't know what is lacking in them to restrict them from being actual milk chocolate (they contain skim milk and cocoa. That's not enough?) but they have a fudgy melty taste that no "milk chocolate" product mimics, and I get cravings for them once a year or so. I'm a foody, but I'm no food snob. *eats another gold coin*
