As I keep giving Sora as is, the remaining potions disappear, too. I never thought he could eat 58 potions at once. I read the ecology of the slime in the book. Still, I could not tell about the amount of food they eat, which was only written as [varies for each individual]. So I'm not sure whether Sora eats a lot or if it's normal, but because his size is a little bigger than my hands, he seems to be a glutton.
