The lovable pink Nintendo character, that goes by the name of Kirby.
When Kirby sucks up air, he turns into a puffball

a sphere made of massive amounts of tissue paper, that is methodically made into flower like shapes. They are all then put together by a "Kippy" a beautiful, voluptuous mythological creature of the forest of great crafting skills. "Kippies"prefer a life of peace and solitude but are often attracted to small gnomes that live throughout the forest, leaving them exhausted and therefore limiting their puffball making abilities.
A Kippy made her 1,972nd "puff ball" and let them float heavenly over the gymnasium making a beautiful resting place for all her gnomes. And then she went ni ni cause she was ti ti.

Puffball is a generic non-newbie online user, in a social or bvehavioral context. The word was coined in the early nineties in the Backstage host (moderator) conference (forum) on the WELL, to refer to anyone who was a real handful for a host to deal with or "moderate," including other hosts or oldtimers.

(The term evokes the name of a wild mushroom, the idea of an enlarged ego, and the concept of being ballsy, but it is a pure coinage and not a derivation.
It's semi-affectionate.)
Usage: "If puffball goes off on a rant in the middle of the one-word-sentence game, how do I get him to take that energy someplace where we can respond to it, so the other users aren't all yelling at me to make him conform to the game?"
