So it is not lightly that I say: YOU ARE IN BIG TROUBLE!!!!!
Your miniature posted at http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=255102564 doesn't look anything like Groo and is not Groo and has nothing to do with Groo. And even if it did, if Ral Partha or whoever is trying to pass off anything as Groo, it is UNauthorized and that is a big legal no-no (and not very nice either.)
So unless you want to be harrassed unmercifully by the Groop, you need to remove the "Groo" designation from the ebay sale and if Ral Partha is passing off these hideous minis as Groo, they need to stop.
