I think we all know little cute spirit and the castle spirit (most likely the boy king) are connected or the same being. My little theory is that the tiny spirit has been enhancing ijae objects. Like the spirit chewing on one of the beads in ch. 27. Or him being encased in the handkerchiefs in 30. And the reason he can't help more is because not only that chest being damaged disrupts his power (his form as well), there's only so much he can interfere in the land of the living.
