The Spiky Bush is an in-game flora commonly found in Marsh biomes. It acts as a source of Twigs, like Saplings. Spiky Bushes are not affected by Winter cold and will regrow after 4 game days during both Summer and in Winter. Harvesting Twigs from a spiky bush damages by 3 points.
Spiky Bushes can be dug up with a Shovel and replanted in a new location. This gives a Twig and an equivalent Sapling and is the safer way of getting Twigs, as digging and picking up a Spiky Bush does not damage the player. The bushes themselves can also be used as an effective fuel for Campfires, though they are not renewable. In this regard, they are similar to Saplings and Grass Tufts.
Spiky Bushes can't be planted on Checkerboard Floorings, Wooden Floorings, Cobblestones, Carpeted Floorings, Rocky Turfs, Sandy Turfs, and Cave Rock Turfs, unless it has been planted before these turfs were placed.
- There are two texture sets in the game, one in darker gray the other in very light, ashen gray. This is merely a cosmetic, visual difference and has no impact on the game.
- The Spiky Bush previously had its own icon on the map.
