User blog:Paeony/Wubbox on Gold Island

Can anyone tell me the purpose of putting a Wubbox on Gold Island? I gather you fill it with monsters from it's originating island that have been levelled up and placed on Gold Island. I have also read that the monsters boxed in this manner disappear from Gold as well as the originating island when you do so. Since there are no coins generated on Gold Island, why would anyone want to throw away all that income from fifteen monsters already levelled up to 15? Is there any benefit to having a filled Wubbox on Gold? Why would anyone do that? (I know some people do as I have seen it while visiting other islands.)

Please help me to understand this, as I am really confused, lol.
