Thanks to @Sir Ody for finding most of these. Spent a good week or two finding them. On the map, ttt_mc_island17, you may have noticed a secret room beneath the tower full of ore like this one. You may be either wondering how to get here or you never knew this existed but here it is! These buttons do not to be pressed in any specific order. The order I am putting them in is completely random. These buttons as well are found behind breakable blocks which are slightly distinguishable from others by seeing their outlines. 1. So the first button that you can find is above the tester here. The button can be found in one of the stone blocks directly above the tester. To get to this button, hit around this area to find the breakable block 2. The next button can be found near the stairs behind the tower. The button can be found in the corner below the stairs. To find it, hit directly in the corner below the stairs to find the block and get to the button. 3. The final button can be found in the cave underground which is attached to the tunnels. The entrance to this cave is found in one of the brick houses closest to the ocean. The general area of the button ^ This is seen when you walk out of the entrance to the tunnels. After walking forward from the previous spot, you can spot a wall 3x3 blocks to your left. Hit the uppermost block in the middle to break the block and reach the button Final button Now than you have found the first three buttons, you must go to the corner of the wall which is a wall to the left of the tower. This spot is facing towards the boat After pressing the final button, congratulations! You found the secret room! Hope this guide helped you guys! Bye!
