Zombeeds are created when Zombies drink any kind of Potion of Swiftness. They are really dangerous as they have the same effects as a zombie including the increase of speed which proves as a threat. Zombeeds drop Rotten Flesh and the potion they drank, and they also have a chance of dropping a carrot, an iron ingot, a potato, and depending on if it has any equipment on it can drop an iron shovel, an iron sword, and any kind of armor depending on what it wears.
