As shown in the thumbnail and icon of KIDNEY STONE, Kidney Stone Man appears to be a blocky figure reflecting the red skybox. This is what gives him his colour. He appears to have a white face along with wearing a pirates hat, also red due to it reflecting the skybox. He has long arms, causing him to look like a wall with a head when idle. These long arms give one of the main mechanics, which is that when you press E on your keyboard his arm will extend and you can use it to swing around.
