Rock Woodsman is a Rock Person who lives by himself out in the woods in a wooden house. He makes a brief appearance in "Earth & Water" in a flashback when he is given baby Flame Princess to hold. When he puts Flame Princess down and starts to chop some wood, she goes into his house and sets it on fire.
His body looks to be made of blue rock that is many different shades. His hands and feet are small, but he has long, noodly arms and legs. He wears blue overalls that cover the lower half of his body and an orange hard hat.
- His clothes do not get burned when he holds Flame Princess.
