Aunt Fashi has a little trick to see if her niece is in need of a diaper change. She summons an invisible eye to check on the state of her diaper while a magic screen lets her see what the eye sees. So Ling Ling plays in peace until Aunt Fashi takes her to the changing table for a change if she needs one. This pic is an example of one instance of this while Ling Ling tosses a tennis ball into a basket as Dunkie her basketball plush looks on. (i added a bit more detail around the legs of the diaper in case anyone notices)
