Realm of Trasures - update idea

My 6 years old son has been pirching several ideas for a Minecraft update, and has demanded insistently that i share them with the developer team. His idea consists of some mobs: Gold /Iron / Copper / diamond Fury, These get into a Fury mode and transform blocks blocks around, and after a little countdown these blocks blow-up. A sourcerer summons a giant monster using blocks This monster can only be defeatd by attacks directly into ots brain, sinyou need to escavate the head ( shadows of the colossus style) The sourcer has a force field around him, so any mellee attacke throws you in the opposite direction The final mob is a robot, with a giant claw, the claw can be extracted and used as a weapon, the claw functions as a way to move also, like an arpoon in other games
