I think I saw a budget bin of playmobil recently with one wolf knight in it quite a lot, the one with a brown beard and an open helmet. He was 3 euros instead of 8.
Still didnt get the guy though, would be another faction and I already have plenty of factions. Same store also sold a superset of dragon knights for 6 euros. I am sad to say that even for that price I would not buy it since it comes with a hideous large rock formation in a useless shape.
Come to think of it, those wolf knights pretty much resemble the special plus idea. They have just as much content, aside from the guy with the catapult.
