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.
"Happy Sweets Dream." Vanilla shrinks Ichigo and sneaks her into the Sweets Kingdom, where she meets three baking school drop-outs who are miniature versions of the Sweets Princes. Calling themselves "The Jerks," they try to ruin the Spirits' New Year's festival as revenge for having their magic revoked by the Queen. Ichigo manages to stop them. Of course, it ends up being only a dream...or was it? Yay for filler.
A similar short story appeared on the manga, where Ichigo falls asleep and shrinks to the size of a Sweets Spirit and meets two other Spirits. The trio together then bakes a cake. It's never stated if it was real or a dream unlike the above mentioned episode, which is stated in later episodes to be real, and not just a dream.
The opening is this. Ichigo fraisier et framboise! Happy, happy macaroon. Happiness, made go!
Professional's theme, "Sweet Romance", is equally catchy.
Family-Unfriendly Aesop: Want to teach your best students to be self-reliant? Then play with their emotions and get them to hate you for the rest of your life, and while your at it, test them further by telling them that their way of thinking is wrong, and that they'll never become pastry chefs by being kind and wanting people to smile. They'll understand...
What Do You Mean, It's Not Symbolic?: All of the Sweets Spirits carry utensils around with them. Vanilla, Caramel and Cafe have spoons, while Chocolat wields a fork. That has to mean something, right?
The Woobie: Okay, so she's generally less abused than most examples of this trope, but Caramel just can't seem to catch a break from anyone. It helps that she breaks down into tears at a moment's notice, getting tons of cuteness points while doing so.
