The Toilet is a block you can sit on by clicking the right mouse key and when the "F” key is pressed, will make one of three farting noises. Also, when any items and/or blocks are placed on the Toilet, you can shift and right click it to flush items down the drain, which causes a flushing sound to commence.
The textures are Water, Quartz and Cyan Stained Clay.
The Toilet is crafted using 5 Block of Quartz and one (Smooth Stone) Button. Even though the picture looks like it is a pillar quartz, don't use it. Use regular quartz, I learned the hard way. Place a stone button on the top middle, a quartz block on the top left, 3 quartz across the middle, and one quartz on the bottom middle.
