beefylpIt's generates can accrossable but secret blocks.(It can shake, so it can be noticed. I cant do anythin for it, sorry. But if its in ground and just 1 block, it's hard to notice. And if smooth lighting on, it's noticing.) You must put it in "Repeating Command Block", and do it "Allways Active".
