Forum:Boxing Monsters

Can someone please explain to me how I can get the monsters I buy to the Wubbox? I bought and incubated a Noggin, and it doesn't give me the option to zap it to the Wubbox. It just says sell or place. How can I get it over there? The one I'm doing needs eight of those and you can't breed them. Also, what is the point of boxing a monster? Does it go into the wubbox you are trying to fill? Admin, please delete if not allowed. I read the rules, but am not quite sure if I'm asking this in the right place. Thanks!
