Fairies. They are tiny. (Unless we're talking the True Blood version of fairies, but we won't go there today.) But how do fairies stay so tiny? For starters, they're always moving. Humans don't see fairies often because they're just THAT FAST. Zip. Gone. Also, fairies are constantly preparing food for humans to lure them into Fairyland and out of the real world. Since party hosts rarely have a chance to eat, again, fairies are at a calorie deficiency. To top it off, fairies love to eat light, which is... well, light in all definitions of the term.
