Graveler finds life as a living rock to be extremely unsatisfactory and is a bit envious of those who aren't fated to carry around 200 pounds of dead weight their entire lives. To this end, it has developed a method of moving quickly and rapidly by rolling everywhere, using its many limbs to propel itself forward. This tends to cause rampant destruction wherever it goes, but it doesn't particularly mind. On the plus side, this also means erosion wears down its body a bit faster - extra speed!
