In Anime, mascots and other tiny or cute characters generally love sugar. It often happens that the hero, or more often heroine, will find a small and cute creature, bring it into their room to take a closer look at it just to find out that has a huge sugar addiction. After the initial shock has worn off the startled main character now has to not only hide, but also provide for, something that is 60cm or less tall and eats enough sugar to put a horse in a diabetic coma. On top of this, the mascot's sweet tooth will usually cause trouble for their caregiver at least once, whether or not they find out.
This trope is not necessarily limited to the above situation; sometimes a main but not central character will end up taking care of the sugar-loving mascot and occasionally we'll even see a villain have one.
Compare Mars Wants Chocolate, when aliens become enamored with Earth's food.
- Flower Angel: Kukuru has quite the sweet tooth and will instantly eat any sweet foods that are set in front of him, though this characteristic is only ever prominent in Season 1.
Anime & Manga

- Cardcaptor Sakura:
- Kero constantly eats sweets despite the fact that he not only doesn't need to eat but is also just barely larger than the utensils. This has caused problems on several occasions, including briefly living in another house after getting drunk off chocolates that contain brandy, giving random answers on Sakura's math homework sheets to get it out of the way so she'll buy him pastries and, of course, being fed by Sakura for over a year for his own amusement.

- Sonic X: Bokkun at one point goes against his instructions and helps the heroes twice, with the promise of getting apple pie and strawberry cake as a reward for his efforts. More than a bit odd considering that he's a robot, but there you go.

- Played for Drama in "Dearest Family", when Tikki's craving for candy gets so out of control that she uses her creation powers without her holder to create the biggest galette to satiate her hunger.

Plagg comments that, in a similar incident far in the past, Tikki summoned an 8-day rain of chocolate mousse.
