Night Four of Research:
The eyes; why the eyes? What significance could they possibly play in relation to the sleep cycle? If what I've heard is true and the eyes truly are the window to the soul, could the eyes non-stop movement be the soul attempting to leave the body? Could this mean the king is approaching death? Perhaps. . . but then again perhaps not. Mayhaps I should try observing a pony of less advanced age, and see if their eyes display the same strange movement patterns the king's do. And if not. . . well, then I have to inform the king of some rather unfortunate news. Only further research will tell what the future holds.
I find all my thoughts turning to Rain. The only moments in which I was distracted from the thought of her beauty was during my observation of King Aurum. This sudden influx of pure emotion is strange to me. Maybe food will help distract me from that which I cannot have. As court fool, it would be a great punishment to sire a child, whose doom it would be to eventually replace me. And so I cannot have Rain.
Addendum: The chefs provided me with actual food tonight. They seem to be over their desire to show-up the Earth pony bakers. Fortunate for me, as I do believe all those doughnuts gave me a cavity.
