What does the diamond Minecraft sword do

the-talos-principle

I found a diamond Minecraft sword hidden in the back of the Circumlocution puzzle in C-6, but I couldn't find anything to use it on. Is there anything I can use it on? What can I do with it?

Best Answer

Yes, you can. This is another easter egg.

I can't remember exactly, so just briefly. You can use it on a wall with plants on it to clear the wall from them and read QR code behind them.
