These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ear Worm - Most of the songs are well-known classical or contemporary tunes, and you'll recognize most of them even if you don't recognize the title. This is followed by a song refusing to leave your head for the rest of the week.
Fridge Horror - Well, more like Fridge Depression. Getting Tony's ending may leave you feeling bad about dancing with him while wearing the witch hat.
Fridge Logic - In Tony's ending, he said the only way to break the spell was to dance with a princess at the Ball in Saint-Lyon and win first place. But you're not really a princess, so how did the spell break, exactly...?
The same way the prince's spell could have been broken in Disney's The Princess and the Frog: it doesn't have to be a princess by birth; a princess by official title works just as well.
