[SOLVED] [1.12.2] Naturally spawning entity in multiple biome types

[FlashHUN]

How can I make an entity naturally spawn in multiple biome types? Like, for example, how could I make it spawn in plains biomes, forest biomes and desert biomes at the same time?
 

    @SubscribeEvent
    public void onEntityRegistry(RegistryEvent.Register<EntityEntry> event) {
    	event.getRegistry().register(EntityEntryBuilder.create().entity(EntityShinobi.class).id
    			(new ResourceLocation(References.mod_id, "mobs"), References.ENTITY_SHINOBI).name("RogueShinobi").tracker
    			(50, 1, true).spawn(EnumCreatureType.CREATURE, 45, 1, 6, BiomeDictionary.getBiomes(BiomeDictionary.Type.PLAINS)).egg
    			(16770207, 000000).build());
    	
    }

The spawn method asks for either an array of biomes or an Iterable of biomes. Just create a List and put all the biomes you want in there.

		List<Set<Biome>> biomes = new ArrayList<Set<Biome>>();
		biomes.add(BiomeDictionary.getBiomes(BiomeDictionary.Type.PLAINS));
		biomes.add(BiomeDictionary.getBiomes(BiomeDictionary.Type.FOREST));
		biomes.add(BiomeDictionary.getBiomes(BiomeDictionary.Type.SANDY));
		
    	event.getRegistry().register(EntityEntryBuilder.create().entity(EntityShinobi.class).id
    			(new ResourceLocation(References.mod_id, "mobs"), References.ENTITY_SHINOBI).name("RogueShinobi").tracker
    			(50, 1, true).spawn(EnumCreatureType.CREATURE, 45, 1, 6, biomes).egg
    			(16770207, 000000).build());

 

Alright, but how should I make that list? This gives me an error in the spawn method and I have no idea how to make that list
