Jungle Walls (natural)

Jungle Walls are background walls found in the Underground Jungle. These naturally occurring walls can be destroyed with a Hammer, but will drop nothing. These walls do not stop enemies from spawning and cannot be used for proper housing.

Trivia

 * The third Jungle Wall bears a striking resemblance to Moss Stone from Minecraft, another popular sandbox game.
