Piercer Miniatures?

Today's post about "The Ecology of the Piercer" article got me wondering: have there ever been any miniatures of piercers? Though I've never been a big user of minis, I did own a fair number of Grenadier AD&D figures in my youth, some of which featured a goodly selection of the game's weirder monsters – and make no mistake: the pierce is weird. However, I can't recall any piercers among Grenadier's offerings, at least not those that I owned in the 1980s. Nor can I find any evidence online of any other manufacturers, official or otherwise, that produced a pierce model in those days. 

Apparently, WizKids produces one nowadays (pictured to the left). Looking at it, I suppose I've inadvertently explained why there haven't been any such miniatures before: what purpose would they serve? The intent behind piercers, assuming I can fathom the mind of Gary Gygax (or whoever it was that originally created it), is that its appearance is a surprise. Looking like an ordinary stalactite, no one is supposed to notice it until it attacks. Placing a miniature of it on the table would be a dead giveaway of its presence, thereby negating its one and only purpose. 

On the other hand, there have been a lot of odd Dungeons & Dragons miniatures over the years. I doubt the piercer would have been the oddest.
