The Plant God, also known as "Life God" and "Nature God", or his official name, "Poutas", has been present since The Minecraft World was made. His main existance reason is to grow tall grass, trees, flowers, mushrooms, vines, etc. He is always watching you planting wheat, and after you go away from your farm, The Plant God comes and instantly makes it harvest-able.
Wherever he walks, Whenever he walks, he leaves a trail of Tall Grass, Flowers, Saplings, Mushrooms. He also can turn dirt into grass instantly! Whenever he walks next to empty pots, random plants appear in them! He also turns dead saplings into Oak Saplings!
If Poutas didn't exist, Your world wouldn't have any trees, grass, seeds, flowers, etc.
The Plant God has a Pot helmet, so You cannot see his face. The pot looks similar to the actual pots in Minecraft, so you cannot distinguish The Plant God from a regular pot.
He also gives flowers to villagers, just like Iron Golems do.
But he's not all that good...
The Plant God sometimes destroys redstone contraptions, and advanced machines, because of his supernatural powers. He destroys some redstone, to grow tall grass, Dispensers are blocked by vines, Hoppers are blocked by layers of grass, and he uses your water buckets from your chests/dispensers to grow plants! How rude!
