"All right then, keep your secrets"

Just a small, silly advancement I thought of, for breaking a block of suspicious sand/gravel, accidental or otherwise, cleverly titled "All right then, keep your secrets", a line Frodo says to Gandalf in the beginning of Fellowship of the Ring. Not only is it a clever use of the quote, a classic characteristic of many current advancements, but it also gives a little laugh for a much needed morale boost to the unfortunate player breaking their first suspicious block.
