The Copper Golem was one of the mobs that could end up in Minecraft. Ultimately, however, the players decided to have something else in the game.
The Copper Golem is a very interesting mob that appeared in the voting for creatures that can be later added to the game. This mob lost, but the community liked it so much that players created it anyway.
Today, the Golem functions as a special add-on, and, seeing the reactions of the Minecraft community, it is doing really well.
The Copper Golem has been introduced anyway
Unfortunately, this is not an official release, but only a mod, at an early stage of development. However, it already has all the behavior and mechanics pre-programmed, it basically looks like it was created and released by Mojang.
You could easily fall for the fact that the Copper Golem is already in Minecraft. Unfortunately, we will have to wait a little longer for this. In theory, you can download the Golem add-on from the website:
However, the mod is surely still a little bugged. If you want to install it, you definitely have to accept that.
