Okay, I understand lots of questions on this subject but it seems like at level 25(close to bedrock), I hear a slime slapping some times around me BUT when I start mining, nothing is there. This happens mostly when I place glowstone as the floor a little and as well as place torches, I even tried digging it out but still nothing, and the roof is REALLY high. I even have a ravine close to it but it is not close enough.. Only for water to be heard.
Can anybody give me some HUGE advice on what I am doing wrong? Please and thank you!
