Toki's first chirp could be translated as: "Who are you?" Toki chirps happily as you pet it and simply says he will do favors for you if you ever bring him food- a high honor, and an animal-speaker only deal! One feeding one task and he will accept normal owl food. Though what favors a bird owned by the supreme kai of time could possibly do for you is beyond your ken. Perhaps he has some mystical properties to him? There has to be SOME reason why this place was named the "time Egg" after all! He then flaps away if you don't have any food for him yet. He was just letting you know this is an option, as for how you feed him and utilize these favors when your separated by two separate time periods and whatnot, I'll leave that up to your own creativity.
