Humans (later renamed Monsters) are mobs which take the form of clones of the default skin. They used to be created by pressing G while playing in Classic mode, but this function was later removed. If the player has a custom skin, any humans created will still use default skin and will not assume the look of the player. Humans could not create or delete blocks, they would just move around the map aimlessly, walking in slightly imperfect circles and jumping occasionally. Humans were affected by solid blocks, but strangely not liquids, walking through them as if they were air.
