I was looking at the /shop spawner various selections and I was wondering what the prefixes on some of the spawners meant, such as Diamond Ghast Spawner, or, Emerald Giant Spawner, does it mean they spawn that type of material? It would make sense if that is the case. I see there is also a Iron Golem Spawner. I kind of understand the Iron Golem one though. If anyone could inform me on the matter it would be much appreciated.
