The description says: When first placed on an island, the Wubbox is a box that does nothing until you box (feed it) one of every 'regular' monster that exists on that island (except the limited edition monsters, the ethereal monsters and the legendary monsters).

I finally saved enough for a Wubbox for the plant island. But most of my monsters are level 15 monsters and only one of each exists. Question is can I first place the Wubbox then slowly breed 'new similar regular' monsters before boxing them. I don't wish to lose my regular monsters after working so hard to get them on gold island.
