Rocks and Cliffs are natural geographic features found throughout the entirety of Lumberland. These features of Lumberland are rectangular in shape and are often really tall. They are made of the 'slate' material. Rocks and Cliffs are brown and often pile up on each other, becoming higher, denser, and taller as they reach up to the Volcano. This most likely means that these rocks are part of the Volcano and/or old lava flows. Thus, if this is true, every rock and cliff on the game is considered part of the Mountainside.
