Friendly copper golems

A new type of golem created with either cut copper or copper blocks. The same build as endermen but slightly thicker arms. They oxidise over time and attract lightning. These golems are much weaker than iron golems and don't protect villages, instead being totally loyal to the player (won't fight back if you hit them) Their perks are that they move quicker and have more range. As they oxidise they become less hostile to aggressive mobs and in stage 3-4 of oxidisation they will not attack or be attacked by any mobs. At stage 4 they also move slower. Being struck by lightning removes one level of oxidisation and will also make any mob in a 5x5 range of it be struck aswell. It will oxidise faster in water and become immobile in water at stage 4 (can be protected from water and oxidisation with wax) They stay in a 20x20 range of lightning rods (don't bond to individual rods and will stay in a range covered by two rods such as 40*20) They will have dark or glowing eyes based on if a jack o lantern was used when creating them and this can be changed later with a bucket/flint and steel. Their overall purpose is more to be pets than security guards which is why they aren't stronger than iron golems.
