The Groundskeeper

The Groundskeeper is a humanoid entity with two glowing eyes and grey/dirty skin. The bones of its arms are exposed and are covered in vines. It wears gardening equipment, such as boots, overalls, a shirt, and a hat. On its belt is a keychain. It carries around a large scythe. Behavior-wise, the Groundskeeper is by far the most unique entity in the game, with multiple phases and states depending on what either the player does or what happens in the environment. Normally, the Groundskeeper is passive, as it will clean patches of grass. While not fully recommended, the Groundskeeper will not kill the player if you touch grass while it's occupied, allowing the player to maneuver around the grass in risky scenarios. Going on and off the grass or simply staring at it for too long will cause the Groundskeeper to start grunting and stare at the player while approaching them. If the player stops triggering the Groundskeeper, it will make either a "watching you" gesture or a slit-throat gesture and return to its passive state. Groundskeeper is heavily implied to be related to Grampy, as it's referred to as, "Sonny" by Grampy. While The Groundskeeper does attack you if it sees you stepping on grass, it is otherwise neutral towards you and will even help you in scenarios involving other entities. This includes killing Mandrakes and Eyestalk, pointing out Monuments, and fighting off Bramble. It is also one of the few entities to speak a human language.
