Building a Clinic
To create a clinic, you need to build 16x16 square of natural rubber blocks on flat land surrounded by at least one open block of land on all sides (preferably more). Your 16x16 square must have the following pattern: four 7x7 white quadrants separated by a red cross 2 blocks wide. Once you have your 16x16 square of blocks built, you then add a lever to the wall of your choice and flick it. Your clinic will automatically generate.
