Moss

Moss is a grass-like plant plant that grows on Stone Blocks. It comes in five colors, and one color can be found throughout each third of a given map (three colors per world), either randomly on cave surfaces or in "moss chambers" with a matching mossy stone wall. Moss sprouts fuzz that can be cut like grass weeds, or can be collected using a Paint Scraper, where it can be placed on stone or Gray Bricks, or used to craft mossy stone walls. Mossy stone requires one more hit to break than clean stone. Moss will be destroyed if the stone block it is on converts to ebonstone, crimstone, or pearlstone.

Lava Moss is a special variant of moss that can only grow in the lava layers of the Cavern. Fire Moss glows in the dark.

Glowing Mosses are special variants of moss that grow in much larger areas than standard moss, and glow in the dark similarly to lava moss. It comes in three versions: Krypton, Xenon, and Argon.

Spread

 * Moss slowly spreads across exposed Stone Blocks and Gray Bricks. If the player does not have access to a Paint Scraper to collect moss with, a player can grow extra moss by building "bridges" of stone for existing moss to grow across. Moss cannot grow or spread above zero depth.
 * The Staff of Regrowth can be used on Stone Blocks or Gray Bricks to grow moss at any depth. The type of moss will vary depending on the proximity to other types of moss. As such, one can spread the Fire Moss from the cavern's lava layers all the way up to the surface.
