Mushroom Grass

A type of short grass that only grows on mud. Mushroom grass produces not only blades of grass like all grass, but mushrooms of various sizes. The smallest ones are just under knee-high, and the tallest are multiple stories tall. These mushrooms are much more dense than most mushrooms, and can be used as effective materials for housing and furniture.
Mushroom grass, whether grass, moss, or mushroom, glows. Not only that, but when there is enough of it present, it creates an aura of perpetual darkness, so it is always night time, even on the surface, in what would otherwise be sunlight.
The unnamed robot acquired a sample of mushroom grass after learning about it from Cherry. Once it got a chance, it grew the grass on Daenc Hydrax 4 behind Castle Rustspring using the dirt and water it got from Zombieland using its Matter Manipulator Bracer.
