Combine 11 of the same (or different, just to be tricky) icons to get..VOLTRON! Master of all the icons and it does...nothing else. It just is shiny and sits there. A monument to your assemblage of...stuff. An achievement of towering .. achieving.
Maybe once a day it can glow or something, or spit out little pixies that sweep up all the excess dust from your floor, and vanish. Or something else. But overall..not much. It could have some lights on it, if we had night-time, but we dont. Its like perpetual daylight. Its like those Road Runner cartoons, did you ever notice that they never ran around at night? Whats up with that? Creepy.
Voltron the Icon doesnt have to explode, but that would (of course) be a super cool feature, doubly so if it includes the 'shower of blood' effect, and triple if its sparkly blood (or explosions).
It doesnt have to come with onion rings but of course I wont turn that down unless there is no honey mustard OR nappykin, cuz I messy.
It doesnt need to dance either, cuz it would probably step on me and squish me and i'd get all teary eyed cuz im sensitive.
OK ALSO: You could get all the icons to make it, then they get scattered all over Ur so you have to go get them. This would give folks something to do, and as you get them you can assemble your new Voltron(tm) Icon and it would make assemblage noises like the machines we assemble. Or something. Or, it can just sit there in a pile and you put it together, which would be boring. Having to get them from all over the place would cause much mirth and merriment, unless you are too lazy to actually walk and get your parts for your VOLTRON ICON (patent pending).
I guess thats about it until later. I ate all my crayons.
