LOST MONEY

Ever feel like: OMG thats such a cool zoid i have to buy it!" ? I have a LOTLOTLOT and basically i lose a llooooottt of money buying these zoids, by the time i finish building them theyre just sitting there in my closet for 5 years waiting to be played with. I just wanted to know this(My reason for this random post) what do people do with the zoids if they have like 72 of them? I would make a museum but thats just me...what do you do?
