Note: If you want to use the custom mobs used in the lucky blocks for challenge games right click a mob with soulstone then right click anywhere on the ground to spawn the mob or you can use the throwable spawn eggs but these special mobs cant be attacked and chased by iron golems (to spawn multiple you need creative mode)
