I can't get Blixkin Entopop to respond to What Bug Collection (which should triger some text about how he loves collecting bugs, but is missing some pieces, and then mention collecting them in a box and that he has a list) or "What Bug Collection Box" which should prompt him to give the 6 slot combinable container. He DOES respond to what list (you must turn in the list with the combined box) but it doesn't do much good without the box.
This is one of the most classic quests.
