Well you have now:
Sculpted by Rick Priestley, who comments:
Ah - I think that's a Bouncing Vrubee (or some such) sculpted for Asgard back in the day - pre-dates RT by quite a few years - not sure if it was ever officially released though as it's not on the Stuff of Legends site.
This one is in Bryan Ansell's collection.
Go on, admit it - you NEED one of these...
