You can't pick up monster spawners in Minecraft. You can use a mod like too many items to give yourself monster spawners. To break them, the quickest way is a pickaxe
Yes. If you switch to peaceful, monster spawners will stay there, but they won't spawn any monsters.
No, the monster spawners are not available as a placeable block, even on Creative.
They are usually found deep down in the bowels of the game. You have to listen for the creepy music to come, and then try to track it down. Tip: to stop them from spawning, put torches on every open space possible.
You can find iron ingots in chests next to monster spawners. But because monster spawners are rare then it would be a lot easier just to mine until you find some iron the melt it in a furnace! :)
Monster spawners do not (as of the version 1.3.1) ever contain creepers naturally. It is possible to get a spawner that spawns creepers by editing the game's code or by using mods.
You can only find mossy cobblestone around monster spawners also in dungeons and strongholds!
No, there are no creeper spawners naturally. Additionally, monster spawners will not spawn endermen or passive mobs (i.e. pigs, chickens, cows, etc.). You can although, download something such as not enough items, to obtain one.
In Minecraft, a monster spawner is a block that spawns specific types of mobs (monsters) at regular intervals. When a player is within 16 blocks of the spawner, it will produce mobs based on its type, such as zombies, skeletons, or creepers. Spawners are commonly found in dungeons, mineshafts, and other generated structures, and can be used to create mob farms for collecting resources. Players can also use silk touch to harvest spawners, allowing them to relocate them for their own use.
It doesn't matter which difficulty setting you are playing on. The seed that the world is in generates the dungeons in different areas. Some seeds generate dungeons that are surface-level.
Mob spawners generate naturally in dungeons, strongholds and abandoned mine-shafts. Dungeon spawners can be either; Zombie, Skeleton or Spider. Stronghold spawners will spawn only silverfish and mineshaft spawners spawn only cave spiders. There are mods you can install to change what spawns in a spawner or to be able to pick a spawner up. You can also place spawners in creative mode, but they will only spawn pigs.
monsters do not spawn from monster spawners in Peaceful mode. Peaceful mode prevents hostile mobs from spawning naturally and also from monster spawners, ensuring the game remains free from any hostile creatures.
