For the rulers of Equestria, there's need for a special kind of meal, one that can fuel their magic. That meal, of course, is ponies. These ponies are usually voulenteers, but some can be prisoners of war and crime. They spend a full year being prepared for their role, manes and tails shaved off and wings/horns removed. They're also fattened up to the liking of the princess they're assigned to.

Luckily, they reform each time, after what they add in magic and fat is used up of course. This can take years, if not decades or centuries. When they reform, they go right back and get ready for the next time. Here, we see Twilight's first go at this special meal, and loving every second of it.
