Approach any «puddle» with a length of 4 blocks, stand at the edge looking towards the opposite «shore», and run the macro. Every 55 minutes, the character will sink into the water for a few seconds. Thus, you can leave the computer turned on at night and not be afraid that you will be overtaken by the «dirty» event (or, if it does, then no more than 55 minutes :))
Download the program (Download) and go to the macro editor
press the button «Open file»
and select the downloaded file
assign a macro to a key and run the program
