First to know that all the people involved have played the amazing mirror, and have witness the incredible power of kirby and galaxia in game, and of course the copy ability. And we have all played Brawl.
"I want to become a ***", mostly monster, without losing ourselves or even shapes, a fusion of sorts, which is one thing kirby is known for. So we seek power to absorb other things and transform ourselves (seriously I was into resident evil, mostly tg when I'm in primary school),(and suck up any adult who are too annoying) and first we talked about making pills that would do the trick (possible with alchemy, and even that takes years of prep and certain not possibly when the majority of us only see it in fiction) or believe ourselves to become monster really hard (even though there are solid evidence that many religion only have their god/ goddess with massive number of believer as they are brought to life) (and that include work of fiction) and a offering of cake was prepared. But as we are only teens and clueless about magic, and we try to offer a cake, which was particularly expansive for us and try to summon Kirby on a full moon, hoping he would descend on earth and transform us. But as it clearly failed the third try, we simply give up.
And as a warning:
1. Kirby never cared about granting others his power as he is simply a mass cannibal.
2. Despite his small size, Kirby and wipe us out easily.
3. There are safer ways to do it, though instantly become a master of various arts are not possible.
4. Never try to summon him.
