My idea for Minecraft is a mob that can function like redstone. This mob would be basically like a creepy monkey, with bulging yellow eyes and a big head. Also, it would have wires for fingers. These mobs would join in groups to form into redstone contraptions. There would be different variations of these for different parts of redstone contraptions as well as special variations for the beginning of the contraption and a wild one.
The redstone mob (10 health for normal and 15 for special variations) would not be a peaceful one. This mob would replace regular redstone in places such as the jungle temple (and many more dungeons that could be created.) I think it makes more sense because a fully blown redstone trap in a dungeon doesn't make sense in a singleplayer world as there is nobody to build such a thing. As well as forming into traps, these mobs could fight on their own. They could pose a serious threat to players who want to mess with the dungeons and cheat their way out of the traps. They would come out as a group ant take turns attacking the player. Also, the beginning of the contraption monkey (extra small) could stun the player for a bit, allowing the other monkeys to form into a circuit and deliver a damaging shock to the player, dealing 10 damage. This could make it a good way to punish players who try to cheat to get out of the traps.
The redstone mob would have a very rewarding drop. When killed, they drop something called shock powder. This powder could be crafted into redstone blocks and stacks of nine redstone dust to create a shocking version. These redstone variants shock anyone who touches them and deals 2 damage. Also, anyone who tries to break it will take 5 damage. To avoid being shocked, a block called the whitelist block can be created. When attacked to redstone, anyone whose name is listed on it (by right clicking) can be whitelisted for this redstone contraption. Also, anyone who tries to add a second one will cause a small explosion (not terrain damaging) and take 15 damage to prevent cheaters.
The wild redstone mob (25 health) would spawn extremely rarely at night. It would be attracted to redstone and would burrow into placed redstone dust. When a player comes near, it will jump out of the dust and attack. It's attacks are low powered, but sometimes (10%) it can stun the player for 5 seconds. It can be tamed using charged redstone blocks. When tamed, it will follow the player and do nothing until the player shift right clicks it, when it will go into the nearest redstone contraption. It will burrow into this and go around the base (faster through charged redstone and powered redstone.) When it encounters a player whose name is not listed on an attached whitelist block, it will go attack them.
These mobs would have a weakness. Anyone willing to mess with these mobs should bring water because these mobs will be dealt 5 damage every second they are in water (also electrifying the water in a 3 block radius which deals 2 damage per second.) This will quickly kill them and let the player get the drops and proceed through the dungeon. However, these mobs will form chains above the water to get to the player. The player can attack these chains, making the mobs fall into the water.
I know this suggestion may seem quite odd, but it can also be interesting. I am creating this thread to see what people think about this suggestion. Criticism is welcome because I want to improve this suggestion. Also, I need name ideas for this mob so that will be good.
