Will the real camman18 please stand up? And accept this challenge?
Hello everyone. Anyone who would like to have a challenge where Diamond Ore doesn't spawn, please try this out.
Also, can we all try our best to get camman18, aka pinkguy to notice this? Let's all take like a solid two minutes to comment on as many of his videos with a tag to him as we can - if you'd like to, of course. Or contact his through some other platform, at one of these links:
