My favorite thing about the Wonka Scrumdiddlyumptious Bar (milk chocolate with toffee, cookie and peanuts) is that the pieces are all different sizes, so you can adjust your serving size in accordance with the size of your craving.
My favorite thing about the purple (actually white) chocolate waterfall? EVERYTHING.
