Well it is simple really.
-First we acquire a hamster and fine tune the ability of conditioning it to eat only cardboard on command
-Second we will get many more and do the same with our fine tuned skills.
-Third buy a throne and dub yourself the hamster lord
-Now this is the important part, since a lord is too important to be seen touching such filth as a box, have the hamsters eat it all away
Box opened, no mess, and a little army at your beck and call

You find the royal king of the hamsters, for you you to ride into battle
