Cavalcade Wargames did some animals, historical miniatures and a range of Armies of the Far East, including Conquistador Ogres an eastern Dwarfs, Orcs and Goblins. These ranges are all exclusively sold by Forlorn Hope Games, who do all their trades via eBay.
Update 31.12.19: The Goblin Ninjas are sold out at the moment and there’s no info on whether they’ll come back.
There have been some more miniatures in the past, you can have a look on Cavalcades Facebook page, but at the time there are only those 3 Ninjas available as well as 9 different wolf riders. A pack of all 3 Ninja Goblins is £6, while a single wolf rider is £4. You can buy these in the shop linked above and also follow Cavalcade Wargames on Facebook and Twitter. The picture belong to Forlorn Hope Games, who you can also find on Facebook.
