It’s all about sugar

The Devilz Avocaat doesn't like lemonade. It turns him into a fluffy duck. Doesn't like sweet things in general, prefers sausages and steaks. But he has dealings with Sweetie Glut, a sugar baron in a world where sweetness is a powerful fuel.
Devilz Advocaat: Sweetie, I thought we promised never to go there again. That old witch’s curse, it’s a ruse. I mean it. You don’t believe its true do you?
Sweetie Glut: Shall we prove it then?
Devilz Advocaat: I’d rather not get that horrible stuff on me. I despise it for other reasons. One, I don’t like lemons and two I hate things that are transparent. And three, I hate sticky situations.
Sweetie Glut: Mmm. I rather like it.
Devilz Advocaat: Well you like everything sweet.
Sweetie Glut: Ha.
Devilz Advocaat: Me, I’m more a fan of snags and stakes

Sweetie always has a stomach ache, so doesn’t tend to move from her resting spot. But if anyone needs to know the most rotten things about something Sweetie can tell them (at a price of course: sugar). Sugar can be used to power engines and vehicles. It is the best fuel in the kingdom and Sweetie has a strangle hold on most sugar operatives.
