I'm making a redstone Boss fight.

My idea is a big friendly mining robot has gone haywire and it's up to the player to reset his system and make him friendly again!
I've just finished his face, where he's going to follow the player with his eyes as well as show different emotions
(such as switching to the angry face in phase 2 of the fight)

He will get sad when taking damage, and happy once you've won and reset his system!
