So there is no collective pronoun for Koalas? So we have an opportunity to do that I take it. Posted last weekend my "Unkindess of Ravens" blog is along that line so I think we could have a bit of fun thinking up one. An early one I can imagine is.... A Kool of Koalas, imagine them wearing fashionable Raybans. Or how about, A Kola of Koalas, avoiding a trademark of a certain popular beverage.
