Green, Green Grass of Home

Green, Green Grass of Home (グリーン・グリーン・グラス・オブ・ホーム) is the Stand of the Green Baby, featured in Stone Ocean.

Appearance
The Stand resembles a humanoid in a dark, tribal bodysuit with a mask with four eyes. It has two turbine-like constructions mounted on the sides of its head. Long spikes sprout from the top of its head.

Its size is roughly equal to one-third that of the average plastic water bottle.

Green, Green Grass of Home is deep blue with silvery, metalic body parts in the colored manga.

Abilities
Green, Green Grass of Home automatically protects its user, the Green Baby, through its esoteric power. Although it is small by nature, if a perceived enemy approaches the Baby enough, it will eventually tower over them, making any inherent difference irrelevant.

Green, Green Grass of Home is rather cunning and is shown to exploit its power and the environment to its advantage in order to kill its enemies.

Shrinking
Green, Green Grass of Home causes everything around the Green Baby to shrink the closer they are from it.

Beginning at an undisclosed distance from the Green Baby, anything, be they objects or people, is reduced in size proportionally to their proximity to the Baby. If someone halves the distance their size is halved as well. As such, it's impossible to actually reach the Baby. If someone moves away from the baby, they will grow back appropriately.

Should a person get close enough to the vanishing point, at a point close to the child, Green, Green Grass of Home will manifest itself and attack them. Although it can force its victim onto the Green Baby, supposedly attempting to wipe the person from existence as they vanish into an infinitely small size, it can eventually resort to killing target through more conventional means, such as using its towering size compared to the shrunken victim to crush them.

If the Baby becomes interested in something or someone and goes to pick it up or touch them, they will automatically return to their normal size.

Trivia

 * This Stand's abilities are based on Zeno's paradoxes.
